NOVELTY - Preparing graphene-polypropylene composite material involves heating and melting the polypropylene, adding gypsum powder and carbon fiber, stirring uniformly, heating and stirring at 400-600 degrees C for 1-3 hours. The nano graphene is added, stirred uniformly, and heated and stirred at 300-500 degrees C for 1-3 hours, and the graphene-polypropylene composite material is obtained by cooling. USE - Method for preparing graphene-polypropylene composite material. ADVANTAGE - The method enables to prepare graphene-polypropylene composite material, which has excellent electrical conductivity.
