单壁碳纳米管(SWNTs)在室温边界润滑条件下表现出良好的摩擦学性能。作为PAO基础油的添加剂，单壁碳纳米管可降低对偶钢表面的摩擦磨损。当聚α-烯烃(PAO)中只加入1wt%的纳米管时，摩擦系数为0.08。这一结果是在几个接触压力(从0.83到1.42 Gpa)下获得的。用分析透射式电子显微镜对摩擦测试前后的纳米管进行表征，以了解纳米管在接触区域的行为。
Single wall carbon nanotubes (SWNTs) present interesting tribological properties under boundary lubrication at ambient temperature. Used as additive to PAO base oil, SWNTs lead to a decrease of both friction and wear of antagonist steel surfaces. With only 1 wt% of nanotubes added to polyalphaolefin (PAO), the friction coefficient is 0.08. This result is obtained under several contact pressures (from 0.83 to 1.42 GPa). Characterisation of nanotubes by analytical transmission electron microscopy (TEM) before and after friction testing is used to understand how nanotubes behave in the contact area.
