Super-elasticity at 4 K of covalently crosslinked polyimide aerogels with negative Poisson’s ratio
The deep cryogenic temperatures present significant challenges for the performance of elastic materials. Here, the authors present a low density covalently crosslinked polyimide (PI) aerogels with super-elastic properties at deep cryogenic temperatures.
