▎ 摘　　要

NOVELTY - Preparing graphene -coated polystyrene microsphere comprises (i) ultrasonically dispersing graphene paper powder in methyl pyrrolidone aqueous solution or ethanol water solution, where graphene paper powder is submicron size, centrifuging the dispersion liquid, taking the supernatant to obtain graphene paper hydrogel liquid, (2) mixing graphene paper hydrogel solution with polystyrene microsphere emulsion with positive charge, adsorbing graphene paper on the surface of polystyrene microsphere with positive charge through electrostatic action. USE - The method is useful preparing graphene-coated polystyrene microsphere. ADVANTAGE - The method has unique strong correlation light coupling with ultraviolet magic tape absorption enhancement conversion. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene coated polystyrene microsphere prepared by the method
