| 摘 要： | 综述了近年来聚对苯撑苯并噁唑(PBO)纤维抗紫外光老化改性的最新研究进展，探讨了紫外光降解老化过程和对光老化机理的推测，指出完善PBO纤维的内部结构和添加抗紫外光老化剂均可改善PBO纤维的紫外光稳定性。介绍了几种抗紫外光老化改性的方法，并讨论了它们各自的优缺点。目前抗紫外光老化研究主要集中在如何提高PBO纤维基体和抗紫外光老化剂之间的相容性。

| Abstract: | As a kind of rig-rod-like polymer, Poly-p-phenylene benzobisoxazole (PBO) has received great interest because of its excellent mechanical properties and good thermal stability. The use of PBO fibers, however, is limited due to its low sunlight stability. Therefore it is necessary to study the UV aging and UV aging resistance of the fiber．This article reviews the recent research progress of study in the UV aging and UV-aging resistance of PBO fiber. Further more，UV aging process and photo aging mechanism of PBO fiber is also discussed．The aging resistance of PBO fiber can be improved by perfecting the structure of fiber and adding appropriate UV-aging agent. And some methods of PBO fiber chemical modification are introduced in this article. |
