摘　　要：PBO纤维具有优异的力学性能、化学稳定性及阻燃隔热性能,因此在诸多领域得到应用,但其在紫外线照射下易老化降解,该缺点严重限制了其在户外甚至太空环境下的应用。文章根据抗紫外线整理剂与PBO纤维不同的结合方式,将其抗紫外改性方法分为表面涂层法、原位共聚法及溶液共混法3种,并结合实例总结了各种方法的特征和优缺点,希望能为PBO纤维的抗紫外老化改性研究提供一些参考。PBO fiber has excellent mechanical properties,chemical stability,flame retardant and heat insulation properties,so it is widely used in many fields.However,PBO fiber is easily aged and degraded under ultraviolet,which seriously limits its application in outdoor and even in space environments.Based on the different combination of anti-ultraviolet finishing agent and PBO fiber,this paper classified three types’anti-ultraviolet modification methods of the PBO fiber,that is,surface coating method,in-situ copolymerization method and solution blending method,and summarizes the characteristics,strengths and frailties of these three methods in combination with examples,so as to provide a reference for further research on UV aging resistance modification of PBO fiber.
