Combining photodynamic antimicrobials with nonwovens is prospective. However, common photosensitizers still have drawbacks such as poor photoactivity and the inability to charge. In this study, a photodynamic and high‐efficiency antimicrobial protective material was prepared by grafting bis benzophenone‐structured 4,4‐terephthaloyl diphthalic anhydride (TDPA) photosensitizer, and antimicrobial agent chlorogenic acid (CA) onto spunbond‐meltblown‐spunbond (SMS) membranes. The charging rates for ·OH and H2O2 were 6377.89 and 913.52 μg/g/h. The light absorption transients structural storage remained above 69% for 1 month. High electrical capacity remained after seven cycles indicating its rechargeability and recyclability. The SMS/TDPA/CA membrane has excellent bactericidal performance when under illumination or lightless conditions, and the bactericidal efficiency of Escherichia coli and Staphylococcus aureus reached over 99%. The construction of self‐disinfection textiles based on the photodynamic strategies proposed in this paper is constructive for expanding and promoting the application of textile materials in the medical field.

稳定储存光吸收瞬态和光动力抗菌作用的传统复合非织造布的改性

将光动力抗菌剂与非织造布相结合是有前景的。然而，常见的光敏剂仍然存在光活性差、无法充电等缺点。本研究通过将双二苯甲酮结构的4,4-对苯二甲酰二苯酐（TDPA）光敏剂和抗菌剂绿原酸（CA）接枝到纺粘-熔喷-纺粘（SMS）上制备了光动力高效抗菌防护材料膜。收费标准为·羟基和氢2氧2分别为 6377.89 和 913.52 μg/g/h。光吸收瞬态结构存储1个月保持在69%以上。七次循环后​​仍保持高电容量，表明其可充电性和可回收性。 SMS/TDPA/CA膜在光照或无光条件下均具有优异的杀菌性能，杀菌效率大肠杆菌和金黄色葡萄球菌达到99%以上。本文提出的基于光动力策略的自消毒纺织品的构建对于扩大和促进纺织材料在医学领域的应用具有建设性的意义。
