摘要
聚四氟乙烯(PTFE)因具有独特的物理化学性质,已成为不可缺少的一类特种材料。由于聚四氟乙烯的分子量和分子链规整度较高,使聚四氟乙烯难于熔融加工。为了获得可熔融加工的全氟材料,国内外关于聚四氟乙烯共聚改性的相关研究和报道较多。本文从可熔融加工四氟乙烯基全氟聚合物的结构和特性方面入手,综述了国内外一系列四氟乙烯与全氟第二单体共聚物的最新研究现状,并提出了全氟聚合物今后的研究发展方向。
Polytetrafluoroethylene （PTFE） is an essential peculiar material because of its particular physico-chemi- cal properties. However, some inevitable drawbacks, such as high melting point, high molecular weight and high degree of crystallinity limit the application of PTFE in some special fields. In order to improve the melt processing property of per- fluorinated polymer, scholars came from all over the world have pay many attentions to the copolymers of PTFE. The effect of different perfluorinated second monomer on the structure and characteristics of perfluorinated polymers from the last researches. Moreover, the future research and development direction of perfluorinated polymers was also proposed.
