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%.

Focus, the graphene-based semi-solid grease shows the more outstandingly lubricating property, and the friction coefficient approximately drops to the range between 0.04 and 0.06.By comparing with the graphite-based grease, the friction The coefficients vary about 40% -60% and the wear reduced over 50%.
