NOVELTY - Electrodeposition on a graphene surface involves adding organic solvent, water, 0.05-3 M conductive polymer monomer solution, 0.5-2 M inorganic acid and stirring to prepare deposition precursor solution, adding the deposition precursor solution the three-electrode electrolytic cell comprising silver/silver chloride as the reference electrode, platinum sheet as the working electrode, and platinum mesh as the counter electrode, and then adding 1-100 mg/L graphene, performing electrodeposition while maintaining agitation and the deposition temperature is 20-60 degrees C, washing the deposited product is washed with deionized water and ethanol, centrifuging at 1000-10000 rpm for 1-10 minutes, and then drying at 50-100 degrees C. The volume ratio of organic solvent and water is 0.3-1.3. USE - Method of electrodeposition on graphene surface for preparing conductive polymer film used as protective film for metals and supercapacitors. ADVANTAGE - The method enables electrodeposition on graphene surface and conductive polymer film having excellent binding force with graphene.
