摘　　要：聚丙烯腈纤维(PAN)经羟胺化学改性制得含有偕胺肟基团的螯合纤维(1);1与纳米Cu S反应制得纳米Cu S/偕胺肟复合纤维(2),其结构经IR,扫描电镜(SEM)和X-衍射能谱(EDX)表征。研究了2对大肠杆菌和枯草芽孢杆菌的抑菌性能。结果表明,2表面生成了纳米硫化铜,对受试菌种具有良好的抑菌性能。The amidoxim-chelated polyacrylonitrile（ PAN） fiber（ 1） was prepared by modification of PAN with hydroxylamine. The nano-copper sulfide / amidoxime composite fiber（ 2） was prepared by reaction of 1 with Cu S nanocrystals. The structure was characterized by IR,SEM and EDX. The antibacterial properties of 2 against Escherichia coli and Bacillus subtilis were investigated. The results indicated that Cu S nanocrystals were deposited uniformly on the surface of 2,and 2 exhibited excellent antibacterial properties.
