▎ 摘　　要

NOVELTY - A graphene-based pearlescent pigment composite material comprises pearlescent pigment coated on surface of graphene which has thickness of 0.3-100 nm. Graphite content is 0.01-5 mass%. USE - A graphene-based pearlescent pigment composite material (claimed). ADVANTAGE - The composite material has strong controllability, good repeating character, and low cost. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene-based pearlescent pigment composite material which involves preparing graphite oxide chemically stripped solution, preparing pearlescent pigment dispersion, mixing graphite oxide solution and pearlescent pigment dispersion, heating to 20-100 degrees C, stirring for 1 hour to 1 week to obtain graphite oxide pearleascent pigment, and performing gas-phase chemical reduction or oxidation of graphite-based pearlescent pigment. DESCRIPTION OF DRAWING(S) - The drawing shows a transmission electron microscope (TEM) image of self-controlled graphite oxide/mica titanium pearlescent pigment in which mica titanium pearlescent pigment is uniformly coated on graphite oxide surface.
