Beschreibung
Zusammenfassung:	The invention belongs to the field of preparation of high-performance fibers, and discloses a method for improving ultraviolet resistance of PBO (poly (p-phenylenebenzobisoxazole)) fibers by doping nanoparticles, which comprises the following steps: uniformly mixing ultraviolet-resistant nanoparticles and polyimide (PI) in a blending manner by taking PBO as a core layer, and then preparing the PBO fibers by taking the polyimide (PI) doped with the ultraviolet-resistant nanoparticles as an outer layer. Compared with an untreated PBO fiber and a PBO/PI fiber with a common skin-core structure, the PBO/PI-uvioresistant nanoparticle fiber with the skin-core structure has the advantages that the PBO/PI-uvioresistant nanoparticle fiber with the skin-core structure is better in uvioresistant performance; the modification method is simple to operate and is an anti-ultraviolet PBO fiber modification method with wide application and popularization values. 本发明属于高性能纤维制备领域，公开了一种通过掺杂纳米粒子提高PBO纤维抗紫外性能的方法，该方法以PBO为芯层，采用共混方式将抗紫外
