Graphene as a lubricant additive has excellent tribological performance. This review provides an overview of the synthesis methods, material structure, tribological properties, and applications of graphene-based nanomaterials as lubricant additives.
Reducing friction and wear by improving the tribological properties of liquid lubricants with additives is one of the most important research goals in tribology. Graphene is a typical two-dimensional (2D) nanomaterial, which has outstanding tribological performance when used as an additive in lubricants. In the past decade, various graphene-based nanomaterials have been fabricated by different methods and investigated as lubricant additives. This review aims at comprehensively overviewing the state-of-the-art graphene-based nanomaterials used as lubricant additives. Firstly, the synthesis methods and material structure are reviewed. Subsequently, the possible mechanism of graphene-based nanomaterials on friction-reduction and anti-wear was briefly discussed. Secondly, tribological properties of various graphene-based nanomaterials as lubricant additives were reviewed and discussed. Additionally, the applications of graphene-based nanomaterials in different lubricating scenarios are also discussed. Finally, challenges and future prospects of graphene-based lubricant additives are proposed.
