▎ 摘 要
NOVELTY - A polystyrene based-composite material comprises graphene nanosheets and polystyrene matrix material. The mass ratio of graphene nanosheets and polystyrene composite is 1:(10-100). The average thickness of graphene nanosheets are 3 nm. The average size of graphene nanosheet is 1-5 mu m. The average molecular weight of polystyrene matrix material is 192000 g/mol. The density of polystyrene matrix material is 1.076 g/mol. USE - Polystyrene based-composite material. ADVANTAGE - The polystyrene based-composite material has high thermal conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of polystyrene based-composite material.
