摘　　要：以聚丙烯腈纤维(PAN)为原料,改性制得含有偕胺肟基团的螯合纤维(AOCF),使其与纳米硫化汞反应,制得纳米硫化汞/偕胺肟复合纤维(nano-HgS/AOCF)。运用扫描电镜(SEM)及X-衍射能谱仪(EDX)对样品进行了表征,并研究了纤维对大肠杆菌和枯草芽孢杆菌的抑菌性能。结果表明,偕胺肟纤维表面生成了分散均匀的纳米硫化汞,0.15 g的nano-HgS/AOCF对大肠杆菌的抑菌能力与5.0万单位的青霉素相当,而对枯草芽孢杆菌的抑菌能力与2.0万单位的青霉素相当。The nanesized-mereuric sulfide/amidoxime fiber （nano-HgS/AOCF） was prepared using HgS nanocrystals and amidoxim-chelated polyacrylonitrile （PAN） fibers. The com- posite fiber was characterized by SEM and EDX, indicating that HgS nanocrystals were deposited uniformly on the surface of the chelating polyacrylonitrile fiber. The antibacterial prop- erties of the composite fiber against escherichia coli and bacil- lus subtilis were investigated. The results indicate that the an-tibacterial ability of 0. 15 g nano-HgS/AOCF is approximate to 5 million units of penicillin to escherichia coli, while 2 mil- lion units of penicillin to bacillus subtilis.
