In order to fabricate antibacterial cotton fabric with excellent antibacterial property and laundering durability, amino functional silver nanoparticles (Ag NPs) were prepared by one-step reaction with amino-terminated hyperbranched polymer (HBP-NH(2)) and grafted on the oxidized cotton fabric subsequently. The synthesized amino functional Ag NPs and Ag NPs grafted oxidized cotton fabric (Ag-GOCF) were characterized which indicated that the average size of Ag NPs was 10.8 nm with narrow size distribution and the Ag NPs have been grafted on the cotton fabric. 99.43% and 99.45% bacterial reduction rates were obtained for Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) respectively in case the cotton fabric was treated with 10 mg/L Ag NPs solution to produce Ag-GOCF with 149.88 mg/kg Ag content. After 50 washing cycles, the Ag content of this Ag-GOCF was maintained at 116.08 mg/kg with its antibacterial activity at over 96% reduction level.
为了制备具有优异抗菌性能和耐洗耐久性的抗菌棉织物，通过一步反应用端氨基超支化聚合物（HBP-NH 2 ）制备了氨基功能化银纳米粒子（Ag NPs），并随后接枝到氧化棉织物上。对合成的氨基功能化 Ag NPs 和接枝氧化棉织物（Ag-GOCF）进行了表征，结果表明，Ag NPs 的平均粒径为 10.8nm，粒径分布较窄，Ag NPs 已接枝到棉织物上。当用 10mg/L Ag NPs 溶液处理棉织物以产生 Ag 含量为 149.88mg/kg 的 Ag-GOCF 时，对金黄色葡萄球菌（S. aureus）和大肠杆菌（E. coli）的抑菌率分别达到 99.43%和 99.45%。经过 50 次洗涤循环后，Ag-GOCF 的 Ag 含量保持在 116.08mg/kg，其抗菌活性仍保持在 96%以上。
