▎ 摘　　要

NOVELTY - Preparation of polypropylene/graphene nanocomposite material, involves evacuating high pressure reactor and filling propylene at atmospheric pressure, adding n-hexane, triethylaluminum, diphenyldimethoxysilane and graphene carrier Ziegler-Natta catalyst to the high pressure reactor and polymerizing, under gauge pressure of 0.3-0.5 MPa, stopping the introduction of propylene, adding 10% hydrochloric acid in ethanol solution to terminate the polymerization reaction, washing the product with ethanol and deionized water and drying to obtain polypropylene/graphene nanocomposite material. USE - Preparation of polypropylene/graphene nanocomposite material (claimed). ADVANTAGE - The performance of polypropylene/graphene nanocomposite material is excellent. DETAILED DESCRIPTION - Preparation of polypropylene/graphene nanocomposite material, involves evacuating high pressure reactor at 55-65 degrees C and filling propylene at atmospheric pressure, adding n-hexane, triethylaluminum, diphenyldimethoxysilane and graphene carrier Ziegler-Natta catalyst to the high pressure reactor and polymerizing at 40-60 degrees C for 10-60 minutes, under gauge pressure of 0.3-0.5 MPa, stopping the introduction of propylene, adding 10% hydrochloric acid in ethanol solution to terminate the polymerization reaction, washing the product with ethanol and deionized water and drying to obtain polypropylene/graphene nanocomposite material.
