摘　　要：介绍了近年来聚对苯撑苯并双噁唑(PBO)纤维的改性方法,并对今后PBO纤维的改性方向进行了展望。PBO纤维的改性主要是采用碳纳米管、石墨烯等纳米粒子及第三单体对PBO纤维进行共混复合及原位共聚改性,从而提高PBO纤维的力学性能、热学性能、表面性能及耐老化性能等。今后应加强改性体PBO基体的共聚改性机理及改性体对PBO聚合、纺丝过程的影响研究,探索多种改性技术的混合使用或新的改性技术,从而制备出更优异的高性能PBO纤维。The modification techniques of poly（ p-phenylene-2,6-benzobisoxazole）（ PBO） fiber were introduced in latest years. The modification trend of PBO fiber was outlooked in the future. The modification techniques of PBO fiber mainly comprised the blend composition and in-situ copolymerization modification in presence of carbon nanotube,nano-particles like graphene and third monomer for the purpose of enhancing the mechanical properties,thermal property,surface performance and aging resistance of PBO fiber. The research in the copolymerization modification mechanism of the modifiers on PBO matrix and the effect of the modifiers on the polymerization and spinning process of PBO should be enhanced in the future. And the combination of the multiple modification techniques or the new modification techniques should be developed in order to produce more excellent high-performance PBO fiber.
