To prepare antibacterial cotton fabrics with laundering durability, an organic-inorganic P(DMDAAC-AGE)/Ag/ZnO composite was synthesized by free radical polymerization where the epoxy groups were utilized to form covalent bonds with the hydroxyl groups of cotton fabrics. The surface morphology, crystal phase and chemical structure of the obtained P(DMDAAC-AGE)/Ag/ZnO composite were characterized by XRD, FT-IR and TEM measurements. The resulting P(DMDAAC-AGE)/Ag/ZnO composite-functionalized cotton fabrics exhibited outstanding antibacterial activity and excellent laundering durability. In the antibacterial tests, the bacteriostatic reduction rate was greater than 99.75%, and remained over 99.00% even after 11 washing cycles (equivalent to 55 commercial or domestic laundering cycles). The antibacterial mechanism was also investigated, partly including release of ions and photocatalysis. Moreover, the coated cotton fabric possessed excellent anti-mildew performance and also maintained the basic properties of cotton fabric. These results suggest that the modified cotton fabrics may find potential applications in a wide variety of areas such as sportswears, socks, and medical textiles.
为了制备具有耐洗耐久性的抗菌棉织物，通过自由基聚合合成了有机-无机 P(DMDAAC-AGE)/Ag/ZnO 复合材料，其中环氧基与棉织物的羟基形成共价键。通过 XRD、FT-IR 和 TEM 测量对所得 P(DMDAAC-AGE)/Ag/ZnO 复合材料的表面形貌、晶体相和化学结构进行了表征。所得 P(DMDAAC-AGE)/Ag/ZnO 复合功能化棉织物表现出优异的抗菌活性和出色的耐洗耐久性。在抗菌测试中，抑菌率大于 99.75%，即使经过 11 次洗涤循环（相当于 55 次商业或家庭洗涤循环），抑菌率仍保持在 99.00%以上。抗菌机理也进行了研究，部分包括离子释放和光催化。此外，涂层棉织物具有优异的防霉性能，同时保持棉织物的基本性能。这些结果表明，改性棉织物可能在运动服、袜子和医疗纺织品等广泛领域有潜在的应用。
