A team around Guangtao ZAN from Tongji University, Inspired by the silkworm cocooning processes, has designed a super-foldable conductive carbon material with layered nanofiber network structures.The material can bear one million folds without structural damage and conductivity fluctuations. It features appropriate pores, non-crosslinked junctions, slidable nanofibers, separable layers, and a compressible network which act synergistically to generate a folding construction at the crease.
