| 摘 要： | 采用金属铜的微米粒子和纳米粒子作为聚四氟乙烯(以下记为:PTFE)的改性添加剂,研究了改性后PTFE的摩擦学性能和摩擦转移膜的形成和稳定性。实验揭示了金属微米粒子和纳米粒子对聚合物摩擦转移膜的形成具有不同的机制,分析表明:单独使用微米添加剂或纳米添加剂在提高PTFE复合材料的摩擦学特性方面都具有各自的优势和不足。

| Abstract: | By the analysis of the tribological properties and the forming and stability of friction transfer films of PTFE composites modified by micro and nano metal particles respectively, the different forming and stability mechanisms of polymer friction transfer films are posted in the paper. The experiments and analysis indicate that filler particles have a great effect on improving anti-wear of composites, but also have a defect or shortage in improving the overall properties of PTFE composites purely modified by micro particles or nano particles. |

| Keywords: | composite additives transfer film modified PTFE tribological properties |
