摘要: The graphene-based semi-solid grease with low friction coefficient was prepared by highly dispersed mixing method. The friction testing result showed that the friction coefficient of the graphene oxidebased semi-solid grease reduced from ca. 0.105 of graphite-based one to ca. 0.075, approximately 30% decreasing. Further, the graphene-based semi-solid grease shows the more outstandingly lubricating property, and the friction coefficient approximately drops to the range of between 0.04 and 0.06. By comparing with the graphite-based grease, the friction coefficient decreases about 40%-60% and the wear reduced over 50%.
