This study aims at developing novel methodology to prepare antibacterial cotton fabric with excellent antibacterial durability, and a “grafting through” approach was adopted to enhance affinity of Ag NPs with cotton fiber surfaces. The surface modification was carried out by covalently linking acrylic acid (AA) molecules onto the fibers, then 4-vinylpyridine was copolymerized with the AA moieties as a polymeric binder. Once the coordination bonds were formed between silver nanoparticles (Ag NPs) and the pyridine nitrogen, Ag NPs could be stably immobilized on the cotton fabric. Experimental results showed that the AA-co-PVP grafting copolymer had a significant regulatory effect on the dispersion and particle size of Ag particles, and the resulting cotton fabric presented a high antibacterial property with excellent durability. Even after 120 washing cycles, the bacterial reduction rates of the modified fabric against both Staphylococcus aureus and Escherichia coli retained a level higher than 99%. In addition, other textile attributes, such as vapor transmissibility, water absorbability and flexibility, could be largely retained in the modified fabrics.

通过“直通”策略合成的 4-乙烯基吡啶聚合物锚定在棉纤维表面的银纳米粒子具有高抗菌耐久性

本研究旨在开发新的方法来制备具有优异抗菌耐久性的抗菌棉织物，并采用“嫁接”方法来增强 Ag NPs 与棉纤维表面的亲和力。通过将丙烯酸 (AA) 分子共价连接到纤维上进行表面改性，然后将 4-乙烯基吡啶作为聚合物粘合剂与 AA 部分共聚。一旦银纳米粒子 (Ag NPs) 和吡啶氮之间形成配位键，Ag NPs 就可以稳定地固定在棉织物上。实验结果表明，AA-co-PVP接枝共聚物对Ag粒子的分散度和粒径具有显着的调节作用，所得棉织物表现出高抗菌性能和优异的耐用性。金黄色葡萄球菌和大肠杆菌保留水平高于 99%。此外，其他纺织品属性，如透湿性、吸水性和柔韧性，可以在很大程度上保留在改性织物中。
