Hard or soft? State-shifting new material can be both
Researchers at Waterloo Engineering have created a new material that can go from a soft gel to a hard solid and back again at the same temperature.
The switchability of the material - a combination of supercooled melted salt and polymers that the researchers call sal-gel - means it has two stable and reversible solid states for potential use in a range of technologies including soft robotics, adhesion and adhesives, and aeronautics.
