▎ 摘　　要

NOVELTY - A porous graphene/polyaniline composite film preparing method involves mixing a graphene oxide dispersion liquid, a hydrogen peroxide and a hydroiodic acid uniformly, refluxing the dispersion liquid and filtering the obtained dispersion liquid to obtain a uniform porous graphene flexible film. The porous graphene flexible film is used as a working electrode, an aniline solution used as an electrolyte and formed a three-electrode system with a counter electrode and a reference electrode. Electropolymerization of aniline is performed by cyclic voltammetry to obtain a sandwich porous graphene/polyaniline composite film. USE - Method for preparing porous graphene/polyaniline composite film for use in a supercapacitor electrode material (claimed). ADVANTAGE - The method enables achieving excellent ion transport and charge transfer capabilities by using a combination of an etchant hydrogen peroxide and a reducing agent hydroiodic acid in rapid preparation manner and using electropolymerization method which rapidly polymerizes to prepare a polyaniline composite material that the degree of polymerization is controllable, the thickness of the composite mold is adjustable and has a sandwich structure to improve the electrochemical performance of the composite electrode.
