摘　　要：层状结构的二维材料具有原子级的厚度、层间超低的剪切强度、高比表面积以及表面化学稳定性。其由于独特的性能,引起了润滑领域研究人员的极大兴趣。当二维材料应用于润滑领域时,不仅能够大幅度提高润滑介质的减摩性能,还可以解决传统添加剂的局限性,如分散性差、恶劣环境下失效。本文从二维材料的纳米摩擦机理出发,详细介绍了二维材料的层间摩擦机理和表面摩擦机理;另外,从实验内容、润滑性能及润滑机制等方面也详细介绍了近年来二维材料用作添加剂在油润滑和水润滑等领域的研究进展。2D materials having a layered structure comprise atomic thickness, ultra-low shear strength, the high specific surface area and surface chemical stability. Due to their excellent performances, 2 D materials have attracted considerable attention in the field of lubrication. When 2D materials were used in the field of lubrication, they can not only greatly improve the anti-friction performance of lubricating medium, but also solve the limitations of traditional additives, such as poor dispersion and failure in harsh environments. In this article, the nanoscale friction mechanisms of 2 D materials including friction mechanism of interlayer and surface are summarized. In addition, the application of 2 D materials as additives in the field of oil lubrication and water lubrication in terms of experimental content, lubrication performance and lubrication mechanism is elaborated.
