Hybrid Fiber Based on Reduced Graphene Oxide and Carbon Nanotubes. It mimics internal structure of spider silk, but is 6 times tougher than spider silk and 12 times tougher than Kevlar. It has excellent electric conductivity, and is twistable, sewable and weavable, therefore has multiple applications such as in fiber-type supercapacitor and battery, artificial muscle and exoskeleton, shielding and bullet-proof material, aeronautics etc.
