在微米和纳米摩擦学中，最令人兴奋的材料将是先进的碳材料。其中包括碳纳米管 (CNT)、富勒烯 C60、洋葱状碳和类金刚石碳。然而，对这些材料的摩擦学研究始于 20 世纪 90 年代末，关于环境大气对摩擦学影响的信息有限。研究了相对湿度（RH）对先进碳材料以及众所周知的层状材料（如高取向石墨、二硫化钼和云母）的微观和纳米摩擦学的影响。在高相对湿度下，摩擦力和粘附力变高。除垂直排列 (VA) CNT 外的所有材料均表现出摩擦力的 RH 依赖性。 VACNT不依赖RH的主要原因是其超疏水性。
In micro and nanotribology, most exciting materials will be advanced carbon materials. These include carbon nanotubes (CNT), fullerene C60, onionlike carbon and diamondlike carbon. However, tribology study on these materials started in the late 1990s, limited information of the influence of environmental atmosphere on tribology being available. The effect of relative humidity (RH) on micro and nanotribology of advanced carbon materials as well as well-known lamellar materials such as highly oriented pyro-graphite, molybdenum disulfide and mica has been studied. At high RH, friction and adhesion became high. All the materials except vertically aligned (VA) CNT showed RH dependence of friction. The primary reason for none of RH dependence of VACNT is the super hydrophobic property.
