摘　　要：石墨烯由于其优异的摩擦学性能常作为添加剂改善润滑剂摩擦性能。基于此,综述了石墨烯添加环氧树脂(EP)、聚酰亚胺(PI)、聚四氟乙烯(PTFE)这3种高分子聚合物摩擦性能研究现状,简要介绍了石墨烯的性质以及3种高分子聚合物的用途和优缺点。重点总结了石墨烯添加3种高分子聚合物所得复合材料在摩擦过程中的摩擦机理。提出了石墨烯增强高分子聚合物的摩擦学性能关键在于石墨烯在基体中的分散性和它们之间的界面强度,以及选择合适的材料进行多元添加可以产生多种材料之间的协同作用。Graphene is often used as an additive to improve the tribological properties of lubricants because of its excellent tribological properties.In this paper,the research status on the friction properties of graphene-added epoxy resin(EP),polyimide(PI)and polytetrafluoroethylene(PTFE)was reviewed.The properties of graphene and the applications,advantages and disadvantages of the three polymers were briefly introduced.The friction mechanisms of the graphene composites obtained by adding graphene to the three kinds of high molecular polymers in the friction process were summarized.It was proposed that the key to the tribological properties of graphene reinforced polymers lay in the dispersion of graphene in the matrix and the interfacial strength between them,as well as the synergistic effect between various materials produced by selecting appropriate materials for multicomponent addition.
