Nanotube Foams Flex and Rebound With “Super Compressibility”
Rensselaer Polytechnic Institute (RPI)Films of aligned carbon nanotubes can act like a layer of mattress springs, flexing and rebounding in response to a force. But unlike a mattress, which can sag and lose its springiness, these nanotube foams maintain their resilience even after thousands of compression cycles.
