NOVELTY - The preparation method of graphene oxide plastic involves (1) dispersing graphene oxide in water, adding 1,6-hexamethylene diisocyanate, stirring, cooling to room temperature after finishing the reaction, adding polysorbate, and ultrasonically dispersing to obtain amphiphilic modified graphene oxide mixed solution, and (2) adding diphenyl carbonate and bisphenol A to a reactor, heating at 140 degrees C to completely melt the raw materials, starting a stirring device, adding transesterification catalyst and the modified graphene oxide mixed solution, continuously raising the temperature, stirring to react, washing after finishing the reaction, and vacuum drying to obtain graphene oxide/polycarbonate material. USE - Preparation method of graphene oxide plastic for vehicle lampshade. ADVANTAGE - The method enables preparation of graphene oxide plastic with excellent aging resistance, high-strength, improved dispersibility, and excellent mechanical performance.
