摘要
聚四氟乙烯(PTFE)具有良好的耐高温、耐腐蚀和自润滑性能而广泛应用于电器、航天航空和生物医疗等领域。但随着服役场景的多元化,PTFE仍存在一定的局限性。本文主要从填充、共混、接枝共聚合和表面改性4个方面概述了近年来国内外PTFE研究现状及其性能改性研究进展,总结展望了PTFE产业当下发展的共性问题及未来可能的发展方向。
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.
