                 Abstract: The microstructure of graphene plays an important role in its tribological properties, which is closely related
                 to its synthesis method. Therefore, it is of great significance to clarify the relationship between graphene synthetic
                 methods, microstructure control strategies, tribological properties and lubrication mechanisms for the development of
                 high-performance graphene lubricant additives. Focusing on the synthesis and structural control of graphene lubricant
                 additives, this article reviews a variety of synthetic methods for adjusting the microstructure of graphene, and
                 summarizes the synthetic strategies for stable dispersion as well as the effects of microstructures on tribological
                 properties. In addition, the microstructure evolution and the lubrication mechanisms of graphene are discussed. At last,
                 the problems and the future trend of graphene as a high-performance lubricant additive are pointed out.
