▎ 摘　　要

NOVELTY - Super-hydrophilic self-cleaning graphite alkenyl pearlescent pigment composite material comprises pearlescent pigment, and graphene coating layer coated on the surface of the pearlescent pigment. A fluorocarbon-containing polymer composite is dispersed in the graphene coating layer. The quality of the graphene is 0.1-1 wt.% of the quality of the pearlescent pigment. The mass of the fluorocarbon-containing polymer composite is 0.1-10 wt.% of the graphene and pearlescent pigment. USE - Used as super-hydrophilic self-cleaning graphite alkenyl pearlescent pigment composite material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the composite material, comprising (1) dispersing the graphene oxide-based pearlescent pigment in solvent to obtain graphene oxide-based pearlescent pigment dispersion, (2) adding fluorocarbon polymer composite to the graphene oxide-based pearlescent pigment dispersion, conducting solvothermal reaction at 60-180degrees Celsius for 0.5-120 hours, washing and drying through suction filtration, and obtaining the graphene-based pearlescent pigment composite material without illumination, and (3) using the xenon lamp to irradiate the obtained non-irradiated graphene-based pearlescent pigment composite material to obtain the super-hydrophilic self-cleaning graphite alkenyl pearlescent pigment composite material.
