▎ 摘　　要

NOVELTY - Preparation polyaniline-graphene composite material involves preparing graphite oxide using Hummers method, dispersing 15-25 mg graphite oxide in 1 mol/L sulfuric acid solution, stirring for 1 hour, adding 0.15-0.25 g aniline monomer, stirring for 1 hour, adding 0.35-0.45 g antioxidant, and acid solution of ammonium persulfate, stirring, providing resultant product into a high-pressure reactor, reacting at 140 degrees C for 12 hours, washing the obtained reaction product, centrifuging, and drying. USE - Preparation polyaniline-graphene composite material used for supercapacitor electrode material. ADVANTAGE - The method enables simple preparation polyaniline-graphene composite material using easily available raw materials under mild reaction conditions. The supercapacitor electrode material using the polyaniline-graphene composite material has excellent specific capacitance, stability, durability and reproducibility.
