Life-threatening diseases, especially those caused by pathogens and harmful ultraviolet radiation (UV-R), have triggered increasing demands for comfortable, antimicrobial, and UV-R protective clothing with a long service life. However, developing such textiles with exceptional wash durability is still challenging. Herein, we demonstrate how to fabricate wash durable multifunctional cotton textiles by growing in situ ZnO-TiO₂ hybrid nanocrystals (NCs) on the surface of cellulosic fabrics. The ZnO-TiO₂ hybrid NCs presented high functional efficiency, owing to their high charge transfer/separation. Ultrafine fiber surface pores, utilized as nucleating sites, endowed the uniform growth of NCs and their physical locking. The resulting fabrics presented excellent UV protection factors up to 54, displayed bactericidal efficiency of 100% against Staphylococcus aureus and Escherichia coli, and optimum self-cleaning efficacy. Moreover, the functionalized textiles exhibited robust washing durability, maintaining antibacterial and anti-UV-R efficiency even after 30 extensive washing cycles.

ZnO-TiO2 杂化纳米晶体负载、耐洗、多功能棉纺织品

危及生命的疾病，尤其是由病原体和有害紫外线辐射 (UV-R) 引起的疾病，引发了对具有较长使用寿命的舒适、抗菌和 UV-R 防护服的日益增长的需求。然而，开发这种具有出色耐洗性的纺织品仍然具有挑战性。在此，我们展示了如何通过在纤维素织物表面原位生长 ZnO-TiO ₂杂化纳米晶体 (NCs)来制造耐洗多功能棉纺织品。ZnO-TiO ₂由于其高电荷转移/分离，混合NCs表现出高功能效率。用作成核位点的超细纤维表面孔隙赋予了 NCs 的均匀生长及其物理锁定。所得织物具有高达 54 的优异紫外线防护系数，对金黄色葡萄球菌和大肠杆菌的杀菌效率为 100% ，并具有最佳的自清洁功效。此外，功能化纺织品表现出强大的洗涤耐久性，即使经过 30 次大范围洗涤循环后仍能保持抗菌和抗 UV-R 效率。
