PBO纤维的合成及改性研究进展

Advances in Research of Synthesis and Modification of PBO Fiber

液晶高分子PBO(聚对苯撑苯并二噁唑)纤维是一种高强度、高模量、耐腐蚀的高分子材料,在耐热性材料和力学特性增强材料方面有着广阔的应用前景,被视为继Kevlar纤维之后在航空航天等领域中的新一代超级纤维。对PBO纤维的合成及改性研究作了较详细的概述,并对各种方法进行了比较。

Liquid crystal macromolecule PBO （poly-p-phenylene-benzobisoxazole） fiber, a kind of polymer material with high strengh, high modulus and excellent chemical resistance, has a vast applied foreground in heatproof materials and strengthen materials with mechanics characteristic. It is seen as a new sort of super fiber among many complex materials with advanced construction in aviation and spaceflight after Kevlar fiber is found. This research consists of synthesization and modification of PBO fiber and the synthetic methods are compared.
