Abstract:

Polytetrafluoroethylene (PTFE) is widely used in the electrical, aerospace, and biomedical fields due to its excellent high⁃temperature resistance, corrosion resistance, and self⁃lubricating properties. However, PTFE still has certain limitations as a result of its diverse service scenarios. This article provided an overview for the research status and advances in PTFE modification from the view of performance optimization, focusing on four aspects of filling, blending, graft copolymerization, and surface modification. These approaches have been extensively explored domestically and internationally in recent years. The article also summarized the current problems in the current development of the PTFE industry and prospected its future development directions.

Key words: polytetrafluoroethylene, performance modification, application demands, research progress
