▎ 摘　　要

NOVELTY - Preparing graphene/polyaniline composite material comprises (i) preparing graphene oxide solution using Hummers method, (ii) dispersing graphene oxide solution in an acidic solution in which ammonium persulfate is dissolved to form an aqueous phase, where the concentration of the ammonium persulfate is 0.01-0.04 mol/l, the mass concentration of the graphene oxide is 0.10-0.25 mg/l, (iii) dissolving aniline in an organic solvent to form an organic phase, where the concentration of the aniline is 7.4-7.6 mg/l, (iv) mixing aqueous phase with the organic phase in a volume ratio of 1:1, allow the reaction to stand for 6-12 hours at low temperature, washing and drying to obtain graphene oxide/polyaniline composite material, and (v) soaking graphene oxide/polyaniline composite material with hydrazine hydrate solution and inorganic acid, washing and drying to obtain graphene/polyaniline composite material. USE - The method is useful for preparing graphene/polyaniline composite material. ADVANTAGE - The method: uses polyaniline fibers as wires of different layers of grapheme, thus composite material can significantly improve the carrier transmission efficiency of the electrode material. The composite material has excellent supercapacitor performance, and good application prospects. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene/polyaniline composite material, prepared by above method.
