Abstract: Graphene is a high-performance two-dimensional nano-lubricating material, which is widely used in the field of tribology. This paper introduced graphene’s unique layer structure and surface morphology, endowing it with excellent intrinsic friction properties, including interlayer slip behavior that accelerates incommensurate transitions,and textured graphene surface wrinkle storage nanoparticles reduce its surface friction coefficient. The problems existing in the composite lubrication performance as the third medium are summarized, including the phenomenon of agglomeration and poor dispersibility. This paper focuses on reviewing the research progress of graphene composite lubrication, including introducing it into the lubrication system to prepare composite additives and play its synergistic effect with each additivephase. It is expounded that graphene nanoparticles have the function of repairing the surface of metal materials in the process of fluid cutting, which can effectively suppress the friction temperature rise and reduce the friction coefficient during the cutting process. Using graphene as a reinforcing phase, the composite materials were prepared by solution blending, lamination and sintering, oxidative modification, in-situ polymerization and other molding processes. The methods to improve the synergy between graphene and the components as well as the bond strength with the matrix material are outlined, and the mechanism of improving the anti-friction and wear resistance of the material is summarized. The future research trends of graphene and its composites are prospected, and further research work is proposed.
