首次开发了一种金属有机骨架（MOF）介导的吸附策略来提高聚对苯撑苯并二恶唑（PBO）纤维的抗紫外（UV）性能。本文采用微波辅助一步加热法将UIO-66成功地固定在PBO纤维表面。实验结果表明，与原始PBO纤维相比，纤维的表面能（91.1%）、粗糙度（268.4%）、界面剪切强度（49.0%）和抗紫外性能（66.7%）都有明显提高。通过UIO-66介导的吸附策略，将抗紫外染料柠檬黄进一步固定到PBO纤维表面。有趣的是，与PBO@UIO-66纤维相比，PBO@柠檬黄纤维表现出上级的抗UV性能（进一步高达81.5%）。PBO@柠檬黄纤维的优异抗紫外性能可合理地归因于UIO-66和柠檬黄分子的协同效应。考虑到MOFs和目标材料的功能和功能，我们的工作表明，MOFs介导的吸附策略将有望赋予PBO纤维其他所需的性能和应用，如太阳能-热转换和自我修复能力。
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 PBO@tartrazine fibers demonstrated superior anti-UV performance (further up to 81.5%) compared to PBO@UIO-66 fibers. The extraordinary anti-UV properties of PBO@tartrazine 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.
