▎ 摘　　要

NOVELTY - Preparation of graphene/polyaniline flexible film electrode material involves dissolving oxidant in deionized water to obtain a clear solution, and then uniformly dispersing the graphene oxide in the oxidant solution to obtain a mixed solution of the oxidant and graphene oxide, subjecting the mixed solution to vacuum filtration operation to prepare a graphene oxide film that adsorbs oxidant, dissolving doped acid and aniline monomer in deionized water to obtain an acidic monomer mixed solution, then immersing the graphene oxide film into the acidic aniline monomer mixed solution, and reacting in a low temperature environment to obtain graphene oxide/polyaniline film with polyaniline polymerized on the surface, dissolving the reducing agent in deionized water to obtain a reducing agent solution, then immersing the graphene oxide/polyaniline film obtained into the reducing agent solution, and heating. USE - Preparation of graphene/polyaniline flexible film electrode material used for energy storage device e.g. supercapacitor. ADVANTAGE - The method enables preparation of graphene/polyaniline flexible film electrode material having excellent repeatability, and poor cycle stability.
