Cotton fabric (CF) is closely related to human life, while its inherent porous structure makes it unable to effectively shield the strong ultraviolet (UV) irradiation, and its superior hygroscopicity provides a favorable environment for microbes, resulting in microbes’ proliferation on CF. The UV irradiation and microbes’ proliferation affect the service life of CF and harm seriously human health. Therefore, developing antimicrobial and UV-blocking fabrics is for the well-being of human. Herein, a novel reactive monochlorotriazine terminated quaternary ammonium salt and benzophenone derivative (BCQ) was synthesized to covalently bind onto CF to fabricate an antimicrobial and UV-blocking CF without compromising its intrinsic physicochemical properties and biocompatibility. The antimicrobial rates of CF finished with 10.0 mg/mL BCQ were higher than 99.99 % against both E.coli and S.aureus, and its antimicrobial rates still were greater than 96 % even after 50 washes, while the cell survival rate was more than 99.5 %. Additionally, the UVA and UVB values were less than 0.5 %, and the UPF value CF finished with 50.0 mg/mL BCQ were up to 210.92. Therefore, we provide a strategy for developing an antimicrobial and UV-blocking CF.

通过一步环保策略实现耐用的抗菌和防紫外线棉织物


棉织物 （CF） 与人类生活息息相关，而其固有的多孔结构使其无法有效屏蔽强烈的紫外线 （UV） 照射，其优越的吸湿性为微生物提供了有利的环境，导致微生物在 CF 上增殖。紫外线照射和微生物的增殖影响了 CF 的使用寿命，严重危害了人体健康。因此，开发抗菌和防紫外线面料是为了人类的福祉。在此，合成了一种新型反应性一氯三嗪封端季铵盐和二苯甲酮衍生物 （BCQ），共价结合到 CF 上，以制备抗菌和紫外线阻隔 CF，而不会影响其固有的物理化学性质和生物相容性。10.0 mg/mL BCQ 处理的 CF 对大肠杆菌和金黄色葡萄球菌的抗菌率均高于 99.99%，即使洗涤 50 次后，其抗菌率仍大于 96%，而细胞存活率超过 99.5%。此外，UVA 和 UVB 值小于 0.5 %，50.0 mg/mL BCQ 处理的 CF UPF 值高达 210.92。因此，我们提供了一种开发抗菌和紫外线阻隔 CF 的策略。
