NOVELTY - Lubricant comprises lubricating grease, 0.001-10 wt.% muti-modified graphene powder uniformly distributed in the lubricating grease. The modified graphene powder comprises a surface modified layer including at least one surface modifier comprising at least two functional groups located at two ends of the surface modifier. At least one of the two functional groups and organic functional group on the graphene powder surface are chemically bonded, and the other functional group forms surface characteristics of the modified graphite powder. USE - Used as a lubricant containing graphene. ADVANTAGE - The lubricant has good lubricating affinity.
