Abstract:

Fluorinated organic materials are widely used as the key materials in high-tech industries. The social demand promotes the development of fluorinated organic material. The recent advance of the preparation and application of fluororesins (new fluoropolymers, electroactive fluoropolymers, new perfluorosulfonic acid ionomers, 3D-printing PTFE) and fluoroelastomers (peroxide curable fluoroelastomers, low temperature resistance fluoroelastomers, high temperature resistance perfluoroelastomers, fluorinated Vitrimer elastomers) was described in this review. Especially, the new high-performance fluorinated organic materials for high-tech industries were introduced. Furthermore, this review also prospected the new and versatile strategies for 3D-printing PTFE and fluorinated Vitrimer elastomers. It will be pay more attention to the development of the environment friendly preparation and efficient processing of high performance fluorinated organic materials in the future.

Key words: fluorinated organic materials, fluororesins, fluoroelastomers, high performance

摘要：

有机氟材料具有优异的热氧稳定性、耐化学腐蚀性、耐老化性、不黏性、电绝缘性以及极小的摩擦系数等特性，因此作为一种不可替代的材料广泛应用于高新技术产业。近年来高新技术产业发展对高性能有机氟材料的需求引发了学术界和工业界对氟材料的研究兴趣。依据本文作者的研究经历及有机氟材料的发展方向，本文介绍了氟树脂（新型含氟聚合物、电活性含氟聚合物、新型全氟磺酸聚合物、聚四氟乙烯3D打印）及氟橡胶（过氧化物硫化氟橡胶、耐低温氟醚橡胶、耐高温全氟醚橡胶、全氟聚醚基类玻璃橡胶）的制备科学及应用进展，特别阐述为了满足航空航天、能源、信息等高新技术产业需求发展的新一代高性能有机氟材料。本文也介绍了近期出现的聚四氟乙烯新成型技术及类玻璃氟橡胶。文章指出发展绿色环保和高效的高性能有机氟材料制备及成型加工方法是今后的发展方向。
