▎ 摘　　要

NOVELTY - A polypyrrole/graphene sheet/nickel oxide nanocomposite conductive material (I) is prepared by subjecting graphene sheet, nickel oxide and pyrrole monomer into ultrasonic polymerization at 0-5 degrees C in the presence of ethanol as medium, polyethylene glycol-400 as dispersant, p-toluenesulfonic acid as doping agent, and ferric chloride as initiator to obtain conductive material (I). USE - Method for preparing polypyrrole/graphene sheet/nickel oxide nanocomposite conductive material (I) (claimed). ADVANTAGE - The method enables the polypyrrole and nickel oxide nanoparticles to be uniformly distributed on the surface of graphene nanosheet (GNS) and completely cover the GNS, thus solving the problem associated with agglomeration during pyrrole polymerization, and effectively improving the conductive performance of the polypyrrole.
