NOVELTY - Serpentine/functionalized graphene lubricating oil additive in which graphene oxide is modified by aminosilane coupling agent to obtain functionalized graphene oxide, and serpentine is chemically bonded. USE - Serpentine/functionalized graphene lubricating oil additive. ADVANTAGE - The serpentine/functionalized graphene is prepared in simple and cost effective manner has excellent dispersibility and surface property, good heat conducting effect and good stability of lubricating oil which produces a beneficial effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing serpentine/functionalized graphene lubricating oil additive, which involves: (A) preparing dispersion of graphene oxide by using the graphene oxide prepared by the modified Hummers method as a raw material; (B) adding silane coupling agent, stirring at room temperature for 0.5-2 hours, heating the reaction at 60-95 degrees C for 1-3 hours, cooling to room temperature, centrifuging and separating to obtain functionalized graphene oxide after washing; (C) dissolving serpentine in function, stirring graphene oxide dispersion, heating at 100-180 degrees C for 0.5-2 hours; and (D) standing for cooling, centrifugally separating and washing to obtain serpentine/functionalized graphene lubricating oil additive.
