Method of preparing electroactive molecule grafted graphene doped conductive polymer electrode materials

Provided is a method of preparing electroactive molecule grafted graphene doped conductive polymer electrode materials, comprising: adding a conductive polymer monomer into an electroactive graphene aqueous solution, uniformly mixing and then adding an oxidizing agent, and reacting for 6-24 hours under the stirring condition of -10 DEG C-30 DEG C to obtain electroactive graphene doped conductive polymer electrode materials. The method utilizes the oxygen-containing functional group on the surface of electroactive graphene and electroactive molecules grafted on the surface to perform in-situ doping on a conductive polymer. The anthraquinones electroactive molecules grafted on the graphene surface endow grapheme with good redox activity and dispersity, widen a grapheme potential window, and ensure high conductivity and stability of the conductive polymer after being doped to the conductive polymer. The electroactive molecule grafted graphene doped conductive polymer electrode materials have high energy density and circulating stability as super capacitor electrode materials.
