Heat Sensitive Materials Remember Four Shapes
Heat-Sensitive Material Remembers Four Shapes
Live Science - March 10, 2010
A substance called a polymer usually used to make fuel cells can "remember" up to four different shapes, and revert to each one at different temperatures, according to new research. The polymer, or others like it, could be used in fields ranging from biomedical engineering to space exploration... From a scientific standpoint, PFSA is "not a unique chemistry at all," said Ken Gall, a materials scientist from Georgia Tech who was also uninvolved in Xie's work.
