Now and then we stop to marvel at the feats of carbon nanotube researchers, who use these infinitesimal tubes to build materials of adamantine strength and impressive electrical conductivity. But what if you could marry the robustness of nanotubes to the stretchiness of viscous liquids? You'd be Xu Ming and his fellow Japan-based scientists, who have creating a super rubber that—unlike normal rubber—does not crack and fall apart at extreme temperatures. Xu's team outlines its creation in a study for this week's edition of the journal Science.
Made entirely of carbon, it can flow and stretch slowly like thick honey and spring back to its original form, said [Xu]."It looks like a metal sponge that is porous, it is made from trillions of entangled carbon nanotubes," she said in a telephone interview. "When you stretch and release it, it can come back slowly (to its original shape)." [ABC News]
