Abstract: 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.
