摘　　要：综述国内外纳米粒子填充聚四氟乙烯 (PTFE)摩擦副材料的研究进展 ,对纳米粒子填充后的减摩抗磨机理进行探讨 ,提出“滚珠轴承”、膜润滑和界面束缚作用三个观点 ,分析该项研究在纳米粒子分散技术和纳米粒子与PTFE基体界面处理上存在的不足 ,并结合复合材料界面处理机理、PTFE表面粘结机理和纳米粒子分散机理 ,提出一些新的纳米粒子填充PTFE复合材料界面改性和分散技术的方法。The research work on nano-particles filled PTFE friction materials at home and abroad was summarized. The mechanisms of the friction reduction and anti-wear of the composites, which were interface adhesive, boundary membrane lubrication and ball bearing, were discussed. The disadvantage of the study on dispersion technology of nanoparticles and the interface treatment between nano-particles and PTFE was presented. Some novel methods of interface modification and dispersion technology were pat forward based on composite interface modification mechanism, surface adhesion mechanism of PTFE, and nano-particle dispersion mechanism.
