you get but plastic go well beyond and

you get but plastic go well beyond and today as a material scientist I would

today as a material scientist I would

today as a material scientist I would like to show you why I find personally

like to show you why I find personally

like to show you why I find personally plastic so amazing and what type of

plastic so amazing and what type of

plastic so amazing and what type of amazing thing you can do with but before

amazing thing you can do with but before

amazing thing you can do with but before that have you even realized that plastic

that have you even realized that plastic

that have you even realized that plastic is what our modern life made of just

is what our modern life made of just

is what our modern life made of just take a second look around you you’ll

take a second look around you you’ll

take a second look around you you’ll figure out that the screen is curtain

figure out that the screen is curtain

figure out that the screen is curtain the lightning most of those things

the lightning most of those things

the lightning most of those things contain plastics so the plastic

contain plastics so the plastic

contain plastics so the plastic revolution has already occurred without

revolution has already occurred without

revolution has already occurred without even having years to realize for

even having years to realize for

even having years to realize for instance this morning is the example I

instance this morning is the example I

instance this morning is the example I got dressed and then I checked the

got dressed and then I checked the

got dressed and then I checked the composition of my clothes and guess what

composition of my clothes and guess what

composition of my clothes and guess what more than half of what I’m wearing now

more than half of what I’m wearing now

more than half of what I’m wearing now is actually made of plastics but being

is actually made of plastics but being

is actually made of plastics but being closed plastic also for opportunities to

closed plastic also for opportunities to

closed plastic also for opportunities to be lighter car lighter plane and

be lighter car lighter plane and

be lighter car lighter plane and therefore reduces drastically the fuel

therefore reduces drastically the fuel

therefore reduces drastically the fuel consumption and because plastic can our

consumption and because plastic can our

consumption and because plastic can our nowaday be made transparent colorful

water resistant impact resistant flame

water resistant impact resistant flame resistant and so on and so on they will

resistant and so on and so on they will

resistant and so on and so on they will find application in most of our daily

find application in most of our daily

find application in most of our daily products so tonight when you leave play

products so tonight when you leave play

products so tonight when you leave play the game and try to detect the

the game and try to detect the

the game and try to detect the composition or at least try to fill how

composition or at least try to fill how

composition or at least try to fill how many of the things that you use on a

many of the things that you use on a

many of the things that you use on a daily basis either made partially or

daily basis either made partially or

daily basis either made partially or fully out of plastic trust me you’ll be

fully out of plastic trust me you’ll be

fully out of plastic trust me you’ll be surprised by the results but actually

surprised by the results but actually

surprised by the results but actually what is plastic we hear about it all the

what is plastic we hear about it all the

what is plastic we hear about it all the time but what really it is well plastic

time but what really it is well plastic

time but what really it is well plastic is essentially polymer polymer stand for

is essentially polymer polymer stand for

is essentially polymer polymer stand for poly for many and marisol parts and as

poly for many and marisol parts and as

poly for many and marisol parts and as you remember the first time I heard

you remember the first time I heard

you remember the first time I heard about this concept during a class as we

about this concept during a class as we

about this concept during a class as we just did the teacher made Oliver Stan I

just did the teacher made Oliver Stan I

just did the teacher made Oliver Stan I said we wear monomer so essentially the

said we wear monomer so essentially the

said we wear monomer so essentially the constitutive element of a polymer so as

constitutive element of a polymer so as

constitutive element of a polymer so as you seen

you seen

you seen is video I guess it remind you some

is video I guess it remind you some

is video I guess it remind you some things as such we are quite weak and you

things as such we are quite weak and you

things as such we are quite weak and you can be pushed easily but now as you saw

can be pushed easily but now as you saw

can be pushed easily but now as you saw it in the example before if you hold

it in the example before if you hold

it in the example before if you hold each other hand then we saw a chain and

each other hand then we saw a chain and

each other hand then we saw a chain and then we become stronger so this is

then we become stronger so this is

then we become stronger so this is essentially how plastic are made long

essentially how plastic are made long

essentially how plastic are made long chain of molecular and this procure

chain of molecular and this procure

chain of molecular and this procure these specific mechanical properties so

these specific mechanical properties so

these specific mechanical properties so while plastic that is around us our

while plastic that is around us our

while plastic that is around us our mainly static the new training material

mainly static the new training material

mainly static the new training material science is to go toward smart responsive

science is to go toward smart responsive

science is to go toward smart responsive material so that means that the plastic

material so that means that the plastic

material so that means that the plastic can move can change color can change

can move can change color can change

can move can change color can change poverty and so on it responds to a

poverty and so on it responds to a

poverty and so on it responds to a change in its environment so while this

change in its environment so while this

change in its environment so while this has been studied now for many years

has been studied now for many years

has been studied now for many years not many people is actually aware of it

not many people is actually aware of it

not many people is actually aware of it so I’ve selected few example to show you

so I’ve selected few example to show you

so I’ve selected few example to show you the amazing capabilities of plastic and

the amazing capabilities of plastic and

the amazing capabilities of plastic and give you a flavor of what you can expect

give you a flavor of what you can expect

give you a flavor of what you can expect in a scientific world in a in this

in a scientific world in a in this

in a scientific world in a in this specific field in their coming years so

specific field in their coming years so

specific field in their coming years so here are the three example of chosen the

here are the three example of chosen the

here are the three example of chosen the first one the first area were we gonna

first one the first area were we gonna

first one the first area were we gonna use smart plastic is in textile so if

use smart plastic is in textile so if

use smart plastic is in textile so if you use matte fiber that can sense and

you use matte fiber that can sense and

you use matte fiber that can sense and react to heat and humidity you can

react to heat and humidity you can

react to heat and humidity you can create clothes that keep you dry and

create clothes that keep you dry and

create clothes that keep you dry and fresh when your Jesus eyes can also give

fresh when your Jesus eyes can also give

fresh when your Jesus eyes can also give you a feedback on your exercise there

you a feedback on your exercise there

you a feedback on your exercise there are also application you can also think

are also application you can also think

are also application you can also think of a piece of film that will be able to

of a piece of film that will be able to

of a piece of film that will be able to sense a change in temperature or even to

sense a change in temperature or even to

sense a change in temperature or even to sense a different molecule and give you

sense a different molecule and give you

sense a different molecule and give you directed back as you can see here the

directed back as you can see here the

directed back as you can see here the last example of chosen is a self-healing

last example of chosen is a self-healing

last example of chosen is a self-healing material so now if you have a car and if

material so now if you have a car and if

material so now if you have a car and if you have a scratch on your car how do

you have a scratch on your car how do

you have a scratch on your car how do you do well you have to go and fix it or

you do well you have to go and fix it or

you do well you have to go and fix it or change the paint if you use such coating

change the paint if you use such coating

change the paint if you use such coating in this case you only need to come with

in this case you only need to come with

in this case you only need to come with a heat source or a light source and your

a heat source or a light source and your

a heat source or a light source and your scratch will disappear how great does

scratch will disappear how great does

scratch will disappear how great does that sound much easier and the list is

that sound much easier and the list is

that sound much easier and the list is much longer but for today I would like

much longer but for today I would like

much longer but for today I would like to focus on one specific application

to focus on one specific application

to focus on one specific application which is deformation of a plastic in

which is deformation of a plastic in

which is deformation of a plastic in response to light

response to light

response to light and really just might with my own eyes

and really just might with my own eyes

and really just might with my own eyes without even having enough to look at it

without even having enough to look at it

without even having enough to look at it through a microscope sounds exciting at

through a microscope sounds exciting at

through a microscope sounds exciting at this to me I was very excited the first

this to me I was very excited the first

this to me I was very excited the first time I heard about it and even more when

time I heard about it and even more when

time I heard about it and even more when I saw oh well we could control the

I saw oh well we could control the

I saw oh well we could control the deformation of a piece of plastic so let

deformation of a piece of plastic so let

deformation of a piece of plastic so let me just explain to you how it works and

me just explain to you how it works and

me just explain to you how it works and then I’ll show you the cool thing we

then I’ll show you the cool thing we

then I’ll show you the cool thing we have made recently so to control the

have made recently so to control the

have made recently so to control the deformation of a plastic we rely on the

deformation of a plastic we rely on the

deformation of a plastic we rely on the concept that is the alignment so for

concept that is the alignment so for

concept that is the alignment so for that we use specific molecule that we

that we use specific molecule that we

that we use specific molecule that we call liquid crystal you may have heard

call liquid crystal you may have heard

call liquid crystal you may have heard of them in your LCD liquid crystal

of them in your LCD liquid crystal

of them in your LCD liquid crystal display at home so basically this

display at home so basically this

display at home so basically this molecule look a bit like Mikado and they

molecule look a bit like Mikado and they

molecule look a bit like Mikado and they have their domain advantages as they can

have their domain advantages as they can

have their domain advantages as they can align with respect to each other so now

align with respect to each other so now

align with respect to each other so now you have to realize that we attach them

you have to realize that we attach them

you have to realize that we attach them all together like we did before and if

all together like we did before and if

all together like we did before and if you are able to just push one of the

you are able to just push one of the

you are able to just push one of the molecule to deform or to trigger it to

molecule to deform or to trigger it to

molecule to deform or to trigger it to deform that will be sufficient to pull

deform that will be sufficient to pull

deform that will be sufficient to pull on the chain and to make everything move

on the chain and to make everything move

on the chain and to make everything move so this is what we have done so we add a

so this is what we have done so we add a

so this is what we have done so we add a small amount of a molecule that will go

small amount of a molecule that will go

small amount of a molecule that will go from a straight to bandit state in

from a straight to bandit state in

from a straight to bandit state in response to light so this is shown in

response to light so this is shown in

response to light so this is shown in this animation where you see the yellow

this animation where you see the yellow

this animation where you see the yellow one are the one that will go from

one are the one that will go from

one are the one that will go from straight to bended and by doing so you

straight to bended and by doing so you

straight to bended and by doing so you have very large deformation of your

have very large deformation of your

have very large deformation of your plastic film and that’s also because we

plastic film and that’s also because we

plastic film and that’s also because we use a specific alignment throughout the

use a specific alignment throughout the

use a specific alignment throughout the thickness so you have contraction at the

thickness so you have contraction at the

thickness so you have contraction at the top and expansion at the bottom so

top and expansion at the bottom so

top and expansion at the bottom so that’s basically how it works pretty

that’s basically how it works pretty

that’s basically how it works pretty simple isn’t it and this has been done

simple isn’t it and this has been done

simple isn’t it and this has been done already for many years but what we are

already for many years but what we are

already for many years but what we are essence is shown is that if this yellow

essence is shown is that if this yellow

essence is shown is that if this yellow molecule now can go from the straight to

molecule now can go from the straight to

molecule now can go from the straight to the bend it the straight to the bended

the bend it the straight to the bended

the bend it the straight to the bended state really really quickly then we

state really really quickly then we

state really really quickly then we could make something cool so now we were

could make something cool so now we were

could make something cool so now we were able to make this tiny creature hole at

able to make this tiny creature hole at

able to make this tiny creature hole at the surface and I can imagine the first

the surface and I can imagine the first

the surface and I can imagine the first time I saw it I was playing with it for

time I saw it I was playing with it for

time I saw it I was playing with it for many hours in the lab and it was really

many hours in the lab and it was really

many hours in the lab and it was really fun trying to tame this little creature

fun trying to tame this little creature

fun trying to tame this little creature but well as scientists were as try to

but well as scientists were as try to

but well as scientists were as try to improve what we do so here the

improve what we do so here the

improve what we do so here the limitation that I I felt I had was that

limitation that I I felt I had was that

limitation that I I felt I had was that I steer to scan the light over the

I steer to scan the light over the

I steer to scan the light over the surface of the film

surface of the film

surface of the film pretty lazy so what I wanted to have is

pretty lazy so what I wanted to have is

pretty lazy so what I wanted to have is just to sit down on the button and watch

just to sit down on the button and watch

just to sit down on the button and watch so this is not so trivial

so this is not so trivial

so this is not so trivial so because but one thing I noticed when

so because but one thing I noticed when

so because but one thing I noticed when I was playing with this creature was it

I was playing with this creature was it

I was playing with this creature was it always want to escape from the light so

always want to escape from the light so

always want to escape from the light so what we did it’s not doesn’t sound so

what we did it’s not doesn’t sound so

what we did it’s not doesn’t sound so nice to little trickier that way we

nice to little trickier that way we

nice to little trickier that way we force it to stay in the beam light by

force it to stay in the beam light by

force it to stay in the beam light by just taping it to the substrate and we

just taping it to the substrate and we

just taping it to the substrate and we did it in such a way that you still have

did it in such a way that you still have

did it in such a way that you still have some space real nice space to wiggle

some space real nice space to wiggle

some space real nice space to wiggle around and by doing so we could obtain

around and by doing so we could obtain

around and by doing so we could obtain this type of motion so here what is

this type of motion so here what is

this type of motion so here what is happening is that if you have a pre

happening is that if you have a pre

happening is that if you have a pre curved piece of film then it will deform

curved piece of film then it will deform

curved piece of film then it will deform okay but by deforming it will place

okay but by deforming it will place

okay but by deforming it will place another piece of the material in the

another piece of the material in the

another piece of the material in the light and therefore that will also place

light and therefore that will also place

light and therefore that will also place a new piece of material and so on and so

a new piece of material and so on and so

a new piece of material and so on and so on you get the principle I guess so then

on you get the principle I guess so then

on you get the principle I guess so then we were quite happy but then come to

we were quite happy but then come to

we were quite happy but then come to still when you look at it for long you

still when you look at it for long you

still when you look at it for long you realize that it feels like this thing is

realize that it feels like this thing is

realize that it feels like this thing is kind of frustrated you know it’s like

kind of frustrated you know it’s like

kind of frustrated you know it’s like skip moving on the same spot and it feel

skip moving on the same spot and it feel

skip moving on the same spot and it feel like you want to just set it free so

like you want to just set it free so

like you want to just set it free so that you can just go on its own so we

that you can just go on its own so we

that you can just go on its own so we were wondering how to do that so the

were wondering how to do that so the

were wondering how to do that so the main key that we had to keep in mind is

main key that we had to keep in mind is

main key that we had to keep in mind is that you still need this Precure of

that you still need this Precure of

that you still need this Precure of shape so that you have this shadow and

shape so that you have this shadow and

shape so that you have this shadow and poverty’ in the light but at the same

poverty’ in the light but at the same

poverty’ in the light but at the same time it should be framed to something so

time it should be framed to something so

time it should be framed to something so this is exactly what we’ve done we

this is exactly what we’ve done we

this is exactly what we’ve done we placed it in a frame a plastic frame

placed it in a frame a plastic frame

placed it in a frame a plastic frame obviously that was able that was light

obviously that was able that was light

obviously that was able that was light enough so that could be carried by the

enough so that could be carried by the

enough so that could be carried by the film so without saying more this is what

film so without saying more this is what

film so without saying more this is what we’ve done and this is what we could

we’ve done and this is what we could

we’ve done and this is what we could obtain this was for the first time that

obtain this was for the first time that

obtain this was for the first time that we could made a piece of polymer walk in

we could made a piece of polymer walk in

we could made a piece of polymer walk in the light and as you can see here also

the light and as you can see here also

the light and as you can see here also that because of this specific alignment

that because of this specific alignment

that because of this specific alignment now if you flip it upside down then it’s

now if you flip it upside down then it’s

now if you flip it upside down then it’s also able to walk in the reverse

also able to walk in the reverse

also able to walk in the reverse direction so at this point we were

direction so at this point we were

direction so at this point we were really happy and excited about this so

really happy and excited about this so

really happy and excited about this so we started to share with people and the

we started to share with people and the

we started to share with people and the main question that come after the

main question that come after the

main question that come after the excitement is okay it’s cool but what is

excitement is okay it’s cool but what is

excitement is okay it’s cool but what is it what is

it what is

it what is four so of course we have thought about

four so of course we have thought about

four so of course we have thought about it and this makes things clear is far

it and this makes things clear is far

it and this makes things clear is far from being commercialized and actually

from being commercialized and actually

from being commercialized and actually the funniest application we had came

the funniest application we had came

the funniest application we had came from a journalist who haskers is it

from a journalist who haskers is it

from a journalist who haskers is it possible to put it under my fridge that

possible to put it under my fridge that

possible to put it under my fridge that he would grasp the bread crumble that

he would grasp the bread crumble that

he would grasp the bread crumble that are otherwise inaccessible well maybe we

are otherwise inaccessible well maybe we

are otherwise inaccessible well maybe we don’t know we didn’t thank him in that

don’t know we didn’t thank him in that

don’t know we didn’t thank him in that direction what we are more thinking of

direction what we are more thinking of

direction what we are more thinking of was to apply such material on solar

was to apply such material on solar

was to apply such material on solar panel in the desert because now after a

panel in the desert because now after a

panel in the desert because now after a sandstone the efficiency of your solar

sandstone the efficiency of your solar

sandstone the efficiency of your solar panel will decrease drastically and the

panel will decrease drastically and the

panel will decrease drastically and the only solution that we have now is just

only solution that we have now is just

only solution that we have now is just to bring a full guide and clean one by

to bring a full guide and clean one by

to bring a full guide and clean one by one which is can imagine really

one which is can imagine really

one which is can imagine really time-consuming so now if you put such

time-consuming so now if you put such

time-consuming so now if you put such material onto a solar panel and it start

material onto a solar panel and it start

material onto a solar panel and it start to lay by itself then you can imagine

to lay by itself then you can imagine

to lay by itself then you can imagine that efficient way to just carry the

that efficient way to just carry the

that efficient way to just carry the particle of sand out of the solar panel

particle of sand out of the solar panel

particle of sand out of the solar panel and we’ve tried that in the Lebanese

and we’ve tried that in the Lebanese

and we’ve tried that in the Lebanese show is promises so well this specific

show is promises so well this specific

show is promises so well this specific example remains really specific it shows

example remains really specific it shows

example remains really specific it shows the type of application that you can

the type of application that you can

the type of application that you can think of and the type of deformation you

think of and the type of deformation you

think of and the type of deformation you can have so you will see more of those

can have so you will see more of those

can have so you will see more of those crazy material coming in the market in

crazy material coming in the market in

crazy material coming in the market in the coming years so please don’t be

the coming years so please don’t be

the coming years so please don’t be afraid next time you hear that a new

afraid next time you hear that a new

afraid next time you hear that a new plastic discovery is not only plastic

plastic discovery is not only plastic

plastic discovery is not only plastic more plastic in the ocean can also be a

more plastic in the ocean can also be a

more plastic in the ocean can also be a new way to cue people a new way a

new way to cue people a new way a

new way to cue people a new way a Malaysian way to build houses or with a

Malaysian way to build houses or with a

Malaysian way to build houses or with a new technological development that we

new technological development that we

new technological development that we are not even aware of yet so now knowing

are not even aware of yet so now knowing

are not even aware of yet so now knowing all the capabilities of plastic the type

all the capabilities of plastic the type

all the capabilities of plastic the type of deformation where you can put until

of deformation where you can put until

of deformation where you can put until you use them the only limit is basically

you use them the only limit is basically

you use them the only limit is basically your imagination so now my question for

your imagination so now my question for

your imagination so now my question for you would be how would you see the

you would be how would you see the

you would be how would you see the material of tomorrow

material of tomorrow

material of tomorrow [Applause]
