成功制备了聚乙二醇-碳纳米管（PEG-CNTs）。四球摩擦磨损试验结果表明，PEG-CNTs复合添加剂的承载能力和抗磨性能均上级PEG复合添加剂。采用旋转流延法在云母片上制备了纳米复合薄膜。原子力显微镜的研究提供了深入了解微观尺度上的粗糙度和微摩擦学性能。薄膜中的聚合物是薄膜表面平整的保证，刚性的碳纳米管增强了薄膜的承载性能。
Poly(ethylene glycol)-carbon nanotubes (PEG-CNTs) were successfully prepared. Results of four-ball tribotester indicated that both the load-carrying capacity and anti-wear of the PEG-CNTs were superior to those PEG owing to the additive reinforced by CNTs. The nanocomposite thin films have been fabricated on mica by spin casting technique. AFM investigations provide insights into the roughness and microtribological properties on a micro scale. The polymer in the film is the guarantee of flat surface, and the rigid CNTs enhance load-bearing property of the thin film.
