▎ 摘　　要

NOVELTY - Preparing polypropylene grafted graphene composite material involves modifying and reducing graphene oxide using aniline compounds, reacting the graphene modified and reduced with maleic anhydride grafted polypropylene to obtain the polypropylene grafted graphene composite material. USE - Method for preparing polypropylene grafted graphene composite material. ADVANTAGE - The method enables to prepare polypropylene grafted graphene composite material solves the problem that the graphene dispersing problem of non-uniformly in the matrix, improves the flame retardant property and thermal stability of polypropylene material and mechanical property.
