NOVELTY - Preparing a supercapacitor based on a graphene/polyaniline composite film involves dispersing graphene oxide and aniline monomers in a solvent, obtaining an anilino-modified graphene oxide after the reaction, polymerizing the aniline monomer with an anilino-modified graphene oxide as a carrier to obtain a graphene oxide/polyaniline composite material, adding the graphene oxide/polyaniline composite material to the graphene oxide solution, dispersing to obtain a graphene oxide/polyaniline tube composite film, reducing the graphene oxide/polyaniline composite film to obtain a graphene/polyaniline composite film, assembling the graphene/polyaniline composite film to obtain a supercapacitor based on a graphene/polyaniline composite film. USE - Method for preparing supercapacitor based on a graphene/polyaniline composite film. ADVANTAGE - The method enables to polymerize polyaniline efficiently on the surface of graphene by amine graft polymerization, prepare the graphene/polyaniline composite film, which has good flexibility.
