#15 Smart polymers
In a previous video, #02 Shape memory materials, we presented smart polymers.
Normally inflexible, they become softer after being soaked in hot water, at which point they can be stretched by hand.
Moreover, when this distorted piece is soaked in hot water again, it immediately recovers its original shape. It's amazing.
In addition, we can customize the recovery temperature.
In this video, we made a special apparatus containing three types of smart polymers that recover at different temperatures.
Watch this sequel video to learn another awesome attribute of smart polymers,
and think of how they could be used in your daily life.
