本研究的目的是探讨水蒸气环境对化学气相沉积在硅（001）衬底上的森林状垂直排列碳纳米管（VACNT）薄膜微摩擦学性能的影响。在相对湿度为0 ~ 100%的条件下，用金针尖进行了摩擦学实验。非常低的附着力和0.6-1.3的高摩擦系数。粘附力和摩擦力与湿度无关，这可能是由于VACNT的高疏水性。将这些摩擦学特性与类金刚石（DLC）样品的摩擦学特性进行了比较。
The aim of this study is to probe the influence of water vapor environment on the microtribological properties of a forestlike vertically aligned carbon nanotube (VACNT) film, deposited on a silicon (001) substrate by chemical vapor deposition. Tribological experiments were performed using a gold tip under relative humidity varying from 0 to 100%. Very low adhesion forces and high friction coefficients of 0.6–1.3 resulted. The adhesion and friction forces were independent of humidity, due probably to the high hydrophobicity of VACNT. These tribological characteristics were compared to those of a diamond like carbon (DLC) sample.
