摘　　要：聚四氟乙烯(PTFE)是一种全氟化聚合物,其具有化学稳定性、耐高温、耐腐蚀等特性。但是,PTFE耐磨性能较差。因此,在使用PTFE时受到了极大的限制。为了提高PTFE的耐磨性能,使其得到广泛的应用。采用了各种改性方法,如表面改性、无机填料等。本文介绍了近年来无机填料改性聚四氟乙烯提升耐磨性能的研究进展,并对无机填料改性聚四氟乙烯进行了展望。Polytetrafluoroethylene(PTFE) is a perfluorinated polymer with chemical stability, high temperature resistance and corrosion resistance. However, the wear resistance of PTFE is poor, so the use of PTFE is greatly limited. In order to improve the wear resistance of PTFE and make it widely used, various modification methods have been adopted, such as surface modification, inorganic filler, etc. This paper introduces the research progress of inorganic filler modified polytetrafluoroethylene to improve wear resistance in recent years, and prospects the inorganic filler modified polytetrafluoroethylene.
