▎ 摘　　要

NOVELTY - Preparing polystyrene microsphere composition graphene comprises dispersing the positive electricity modified monomer, styrene monomer and initiator in the dispersion medium, stirring to make it polymerize, preparing positive electricity modified polystyrene microsphere dispersion, controlling the grain diameter of the positive electricity modified polystyrene microsphere generated by polymerization is 1.2-2 mu m, uniformly mixing the graphene oxide dispersion and the positive modified polystyrene microsphere dispersion, adjusting the pH of the dispersed system after mixing is 4-9, making the graphene oxide coated on the surface of the positive electric modified polystyrene microsphere and reducing graphene oxide. USE - The method is useful for preparing polystyrene microsphere composition graphene. ADVANTAGE - The method: provides composition material, which is useful in the preparation of super capacitor, memory or electromagnetic shielding device; improves the dispersibility of the graphene sheets, controls the particle size of the polystyrene microspheres to be 1.2-2 mu m, and constructs a composition material in which the graphene is uniformly embedded in the polystyrene matrix.
