NOVELTY - Preparing an ultra-high molecular weight polyethylene/graphene oxide composite material involves modifying graphene oxide with a cationic surfactant to obtain surface modified graphene oxide. The low-temperature plasma treatment is performed on the ultra-high molecular weight polyethylene to obtain a plasma surface-treated ultra-high molecular weight polyethylene. The surface-modified graphene oxide and the plasma-treated ultra-high molecular weight polyethylene are mixed in a high-speed mixer, and obtained ultra-high molecular weight polyethylene/graphene oxide mixed powder. The ultra-high molecular weight polyethylene/graphene oxide mixed powder is hot-pressed to obtain the ultra-high molecular weight polyethylene/graphene oxide composite material. USE - Method for preparing an ultra-high molecular weight polyethylene/graphene oxide composite material. ADVANTAGE - The method enables to prepare an ultra-high molecular weight polyethylene/graphene oxide composite material, that has high strength and good electrical conductivity.
