随着我国军事装备、空天探测、光电交通等领域的快速发展,其对高性能有机纤维的性能要求不断提高.现有高性能芳杂环聚合物虽有足够优异的性能,使其从分子结构设计走向实际生产应用,但仍存在诸多缺陷,故当前亟待开发综合性能更好的高性能芳杂环聚合物纤维.本文简要介绍了含苯并咪唑结构的杂环共聚芳纶(芳纶Ⅲ)、聚对苯撑苯并二噁唑(poly(p-phenylene benzobisoxazole),PBO)、聚2,5-二羟基-1,4-苯撑吡啶并二咪唑(poly-pyridobisimidazole,PIPD/M5)三种现有高性能芳杂环聚合物纤维分子结构与性能之间的内在关联,总结了三种纤维的制备工艺、应用范围及缺陷不足,综述了共聚改性制备新型芳杂环聚合物纤维的研究进展,并对高性能芳杂环聚合物未来的研发生产进行了展望.
Research Progress in Preparation of High Performance Aromatic Heterocyclic Polymer Fibers
The performance requirements for high-performance organic fibers are increasing with the rapid development of military equipment,air and space exploration,optoelectronic transportation,and other fields.Although the existing high-performance aryl heterocyclic polymers have enough excellent performances to make it from the molecular structure design to practical production applications,there are still many defects,so there is an urgent need to develop a better overall performance of high-performance aryl heterocyclic polymer fibers.This paper briefly introduces the intrinsic correlation between the molecular structure and performance of three existing high-performance aryl heterocyclic polymer fibers,benzimidazole heterocyclic copolymerized aramid(aramid Ⅲ)fibers,poly(p-phenylene benzobisoxazole)(PBO)fibers,and poly-pyridobisimidazole(PIPD/M5)fibers,summarizes the preparation process,application scope,and defects of the three kinds of fibers,and reviews the research progress of copolymerization modification for the preparation of new aryl heterocyclic polymer fibers and also looks ahead to the future research and development of high-performance aryl heterocyclic polymer production.
