摘要
本文采用扫描电镜、X射线衍射和光电子能谱等手段对载银活性炭纤维的表面结构进行了表征和分析，并测试了其抗菌性能。结果表明：载银活性炭纤维表面银颗粒呈纳米级均匀分布，粒径为20～40 nm，其存在形式为单质银；载银活性炭纤维具有优异的抑菌性能，当银含量达到2200 mg/kg时，对白色念珠菌（C.albicans）、大肠杆菌（E.coli）和金黄色葡萄球菌（S.aureus）的抑菌率均可达到99.99%；载银活性炭纤维不仅起到抑制细菌生长繁殖的作用，还起到了一定程度的杀菌作用。
Structure of the silver loaded activated carbon fiber was characterized by SEM, XRD and XPS in this paper, and the antibacterial properties were also studied. The results showed that the silver particles on the silver loaded activated carbon fiber were distributed evenly at nanoscale sizes, the average size of the silver particles was about 20 ~ 40 nm and its existence format was metallic silver. The silver loaded activated carbon fiber had excellent antibacterial performance. When the silver content of the silver loaded activated carbon fiber was 2 200 mg/kg, the bacteria inhibitive rate against candida albicans（C.albicans）, escherichia coli （E.coli）and staphylococcus aureus （S.aureus）exceeded 99.99%. The silver loaded activated carbon fiber can not only inhibit the growth and multiplication of bacteria, but also can kill bacteria.
