NOVELTY - Method for preparing graphene-carbonized fiber sponge, involves (a) washing and drying waste cigarette heads using deionized water, soaking the dried cigarette head in 10 mg/ml graphene oxide solution for 2 hours, which uniformly penetrates the graphene oxide nanosheets to the cigarette end, and wrapping on the surface of cellulose acetate fiber, (b) taking the cigarette end impregnated with the graphene oxide solution, naturally drying at room temperature to obtain cellulose acetate doped graphene oxide, placing obtained product in a tubular furnace, carbonizing at 900 degrees C for 2 hours under argon protection to obtain the graphene-carbonized fiber sponge, and (c) coating the polypyrrole on obtained graphene-carbonized fiber sponge using a chemical oxidation method to obtain graphene-carbonized fiber-polypyrrole ternary sponge. USE - The graphene-carbonized fiber sponge is useful in chemical applications. ADVANTAGE - The method is simple, and the obtained sponge has excellent performance.
