石墨烯作为一种著名的固体润滑剂被广泛应用于微纳尺度的机械装置中，尽可能地降低石墨烯的摩擦是提高这些装置性能的永恒任务。提出了一种通过对衬底进行等离子体处理来降低石墨烯与原子力显微镜（AFM）针尖之间摩擦力的新方法。等离子体处理后的基底通过产生更强的货车德瓦尔斯引力增强了石墨烯和SiO2基底之间的粘附力。无论石墨烯的厚度和AFM针尖的种类如何，增强附着力确实可以降低石墨烯的摩擦力。等离子体处理时间越长，附着力越强，摩擦力越小。摩擦力的降低主要是由于石墨烯的褶皱被抑制和石墨烯调节其原子构型的能力降低的组合作用。这种新的方法将促进石墨烯和其他相关的二维材料作为MEMS/NEMS中的润滑剂的工程应用。
Graphene as a well-known solid lubricant is widely used in micro- and nano-scale mechanical devices, decreasing the friction of graphene as far as possible is a perpetual task to improve the performance of these devices. A novel approach was proposed to decrease the friction of graphene against atomic force microscopy (AFM) tip by plasma treatment of the substrate. The plasma treatment of the substrate enhances the adhesive attraction between graphene and SiO2substrate by generating stronger van der Waals attraction. Enhancing the adhesive attraction can indeed decrease the friction of graphene, regardless of the thickness of graphene and the kinds of AFM tip. Longer time of plasma treatment results in stronger adhesive attraction, leads to smaller friction. The decreased friction is mainly due to the combined action of the suppressed puckering of graphene and the reduced ability of graphene to adjust its atomic configuration. This novel approach will promote the engineering application of graphene and other related 2D materials as lubricants in MEMS/NEMS.
