It is a challenge to synthesize graphene-based sponge via a low cost method.Herein, we propose a facile, economic, and environmentally friendly method to produce ultralight graphene sponge consisting of carbon nanofibers (CNF) and nitrogen-doped graphene using raw cotton and urea through a simple thermal condensation method.The pore walls of our sponge consist of graphene tethered to CNF via carbon-carbon bonds, forming the novel "rebar graphene" structure.Owing to the porous, robust and stable structure, our hybrid graphene sponge shows excellent elasticity, electrical conductivity and adsorption capacity, thereby making it a potential material in many fields such as environmental cleanup and as flexible electrodes for energy storage systems.
