A metal–organic framework (MOF)-mediated adsorption strategy is first developed for improving the anti-ultraviolet (UV) properties of poly(p-phenylene benzobisoxazole) (PBO) fibers. In this work, UIO-66 was successfully anchored onto the surface of PBO fibers by one-step microwave-assisted heating method. The experimental results showed an obviously enhanced surface energy (91.1%), roughness (268.4%), interfacial shear strength (49.0%), and anti-UV properties (66.7%) compared to pristine PBO fibers. The anti-UV dye (tartrazine) was further immobilized onto the surface of PBO fibers via an adsorption strategy mediated by UIO-66. Interestingly, the [email protected] fibers demonstrated superior anti-UV performance (further up to 81.5%) compared to [email protected] fibers. The extraordinary anti-UV properties of [email protected] fibers could be rationally ascribed to the synergistic effects of UIO-66 and tartrazine molecules. Considering the diversities and functionalities of MOFs and targeted materials, our work indicates that the MOF-mediated adsorption strategy would promisingly endow PBO fibers with other desired performance and applications such as solar–thermal transition and self-healing abilities.

聚对苯撑苯并二恶唑纤维上抗紫外线“防护服”的构建：金属有机骨架介导的吸收策略
首先开发了一种金属-有机骨架（MOF）介导的吸附策略，以改善聚（p-亚苯基苯并双恶唑（PBO）纤维。在这项工作中，UIO-66通过一步微波辅助加热方法成功地锚固到了PBO纤维的表面上。实验结果表明，与原始PBO纤维相比，表面能（91.1％），粗糙度（268.4％），界面剪切强度（49.0％）和抗紫外线性能（66.7％）明显提高。通过UIO-66介导的吸附策略，将抗UV染料（酒石黄）进一步固定在PBO纤维的表面上。有趣的是，与[电子邮件保护]纤维相比，[电子邮件保护]纤维表现出优异的抗紫外线性能（进一步高达81.5％）。[受电子邮件保护的]纤维非凡的抗紫外线性能可以合理地归因于UIO-66和tartrazine分子的协同作用。
