Abstract

The fundamental understanding of friction phenomena at atomic level is important in the area of micro-electro-mechanical system and so on. However, the existing knowledges of friction are all based on the Newton mechanics theory and experiments on macroscale. In this paper, the friction between CNT and graphite surface is studied by using classical molecular dynamics simulation. The result shows an anisotropic behavior of friction between two structures, and the symmetry of the nanotube can be characterized by the variation of potential energy as well.

碳纳米管与石墨摩擦的分子动力学研究
在原子水平上对摩擦现象的基本认识在微机电系统等领域具有重要意义。然而,现有的摩擦知识都是建立在牛顿力学理论和宏观尺度实验的基础上的。本文采用经典分子动力学模拟方法研究了碳纳米管与石墨表面的摩擦。结果表明,两种结构之间的摩擦具有各向异性,并且纳米管的对称性也可以通过势能的变化来表征。
