▎ 摘　　要

NOVELTY - Additive composition comprises graphene-polymer, where the graphene-polymer comprises 1-100 pts. wt. graphene, at least a monomer, 1-100 pts. wt. organic solvent, and 0.01-30 pts. wt. organosulfur compound. USE - The additive composition is used for lubricant, and is used for producing an additive. ADVANTAGE - The graphene-polymer additive of the composition has improved dispersion and anti-wear properties which involve lower production cost and simpler production method for enhancing the performance of a moving mechanical system. The graphene-polymer additive of the composition has minimal chemicals composition, and is cost effective. The method for producing graphene-polymer additive is simple. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for producing the additive composition, comprising dissolving graphene in monomers and organic solvent to form a first mixture, dissolving organosulfur compound into first mixture to form a second mixture, and reacting the second mixture at 60-120 degrees C for 12-48 hours to obtain the graphene-polymer.
