Abstract
In this work, the frictional behaviors of carbon nanotubes under various sliding conditions were investigated using Molecular Dynamics Simulation. A single CNT and multiple aligned CNTs were modeled for friction simulation under a normal load ranging from 3 nN to 32 nN. Three sliding directions were chosen to investigate the effects of orientation. Results showed that a lower friction coefficient was obtained under high normal loads for all cases. When a single nanotube was used, the friction coefficient along the 0° direction was the smallest, while simulations with multiple aligned CNTs exhibited the smallest friction coefficient along the 90°direction.
