▎ 摘　　要

NOVELTY - A graphene/polyaniline nanocomposite is obtained by covalently introducing polyaniline composite material nanorod on surface of graphene material. USE - Graphene/polyaniline nanocomposite is used as catalyst carrier and in situ growth-inducing metal nanocluster. ADVANTAGE - The graphene/polyaniline nanocomposite having excellent biocompatibility and electrochemical activity is prepared by simple and economical method. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene/polyaniline nanocomposite, which involves preparing modified graphene oxide by adding graphite oxide into aqueous alcohol system, adjusting pH to 8-12, performing ultrasonic treatment for 10-120 minutes, adding silane coupling agent and refluxing under inert gas for 2-12 hours, preparing modified graphene by adding reducing agent to modified graphene oxide, refluxing under inert gas for 2-24 hours, filtering, washing to neutral, and drying, and forming graphene/polyaniline nanocomposite by dispersing modified graphene in aqueous alcohol system, performing ultrasonic treatment, adding aniline and ammonium persulfate, adjusting pH to 1-3, reacting at room temperature for 1-24 hours, filtering, washing to neutral, and drying.
