Abstract
A continuing desire exists to explore graphene as a lubricant additive and increase the performance of oil/grease products in efforts to acquire a fundamental knowledge of its tribology. As compared to graphite and ionic liquid, multilayer graphene (MLG) as a bentone lubricating grease additive not only provides lower friction and better wear resistance, but also greatly improves the load-bearing capacities and thermal stability of bentone lubricating grease. These benefits are strongly dependent on the formation of a versatile boundary lubricating film, which is provided by the laminated structure and good adsorption action of MLG on the rubbing surfaces, as well as good dispersion of MLG in grease.
