石墨烯是一种原子薄、表面能低的材料，涂覆在各种表面上时，是减少粘着和摩擦的极佳候选材料。在这里，我们展示了用化学气相沉积方法在铜和镍金属催化剂上生长并转移到SiO_2/Si衬底上的石墨烯薄膜具有良好的附着力和摩擦特性。石墨烯薄膜有效地降低了粘附力和摩擦力，几纳米厚的多层石墨烯薄膜具有与块体石墨相当的低摩擦系数。
As an atomically thin material with low surface energy, graphene is an excellent candidate for reducing adhesion and friction when coated on various surfaces. Here, we demonstrate the superior adhesion and frictional characteristics of graphene films which were grown on Cu and Ni metal catalysts by chemical vapor deposition and transferred onto the SiO2/Si substrate. The graphene films effectively reduced the adhesion and friction forces, and multilayer graphene films that were a few nanometers thick had low coefficients of friction comparable to that of bulk graphite.
