摘要: 聚对苯撑苯并双噁唑(PBO)纤维以其优异的特性引起人们广泛的关注,但由于PBO纤维的表面光滑,且化学性质稳定,不易于树脂基体结合,严重影响PBO纤维复合材料的性能。本文简述了PBO纤维的结构与性能。综述了PBO纤维表面改性的方法,包括共聚处理法、纳米粒子处理法、化学处理法和物理处理法。Abstract: PBO fiber has attracted wide attention for its excellent properties,but is difficult to combined with resin matrix for its smooth and chemical stable suface and the performance of the PBO fiber composites is serionsly affected.This paper describes the structure and the preparation of poly p-phenylene benzobisoxazole(PBO) fiber as well as fiber surface modification methods,including copolymerization,nanoparticle treatment,chemical and physical treatment.
