综述了石墨烯微片作为润滑添加剂在油性、水性及固相摩擦领域中的应用进展及其相应的制备方式，包括功能化改性、物理法处理、制备复合材料等。研究了石墨烯微片对材料摩擦系数及磨损率的影响，并采用薄膜润滑、轴承润滑、纳米填充等分析其减少摩擦磨损的作用机理。最后指出石墨烯用于摩擦领域仍有待解决的问题。

The applications of graphene nanosheets as a lubricating additive in oil-based lubes,water-base lubricant and solid lubricant are reviewed.Moreover,the corresponding preparation methods are also summarized,including functional modification,physical treatment and the preparation of composite materials.Effects of graphene nanosheets on the friction coefficient and wear rate of the materials are studied.The mechanism for reducing friction and wear is analyzed by means of referencing thin film lubrication,bearing lubrication and nano-filling.It is pointed out that there are still problems to be solved as for application of graphene nanosheets in the tribology field.
