▎ 摘　　要

NOVELTY - Preparation of polyaniline/graphene oxide nano-composite material involves adding preset amount of graphene oxide to 50 g water, adding preset amount of aniline monomer, processing, obtaining uniform and stable dispersion, adding oxidizing agent and doping acid to the obtained dispersion, stirring-polymerizing, subjecting to suction filtration, repeatedly washing using distilled water and ethanol, and drying in an oven at 60 degrees C for 24 hours. USE - Preparation of polyaniline/graphene oxide nano-composite material (claimed). ADVANTAGE - The method efficiently provides polyaniline/graphene oxide nano-composite material having excellent electrochemical performance and high conductivity, by simple method.
