摘　　要：石墨烯的微观结构在其摩擦学性能中起到重要作用,而微观结构又与其合成方法密切相关.因此,梳理石墨烯的合成方法、微观结构调控策略、摩擦学性能以及润滑机理之间的关系对于开发高性能的石墨烯润滑添加剂具有重要意义.本文作者从石墨烯润滑添加剂的合成与结构调控出发,综述了多种调控石墨烯微观结构的合成方法,归纳了石墨烯稳定分散的合成策略,阐述了石墨烯润滑添加剂的微观结构对其摩擦学性能的影响,探讨了石墨烯的微观结构演变与润滑机理,最后总结并指出石墨烯作为高性能润滑添加剂仍需研究的问题及未来的发展趋势.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.
