纳米硫化镍/偕胺肟复合纤维的制备及性能研究

Preparation and Properties of Nanometer Nickel Sulfide/Amidoxime Composite Fiber

以含偕胺肟基团的螯合纤维(AOCF)为原料,使其与纳米硫化镍反应,制得纳米硫化镍/偕胺肟复合纤维(nano-NiS_2/AOCF)。运用扫描电镜(SEM)及X-衍射能谱仪(EDX)对样品进行了相应的表征,并研究纤维对大肠杆菌和枯草芽孢杆菌的抗菌性能。结果表明,在纤维表面生成了分散均匀的纳米硫化镍,0.18g的nano-NiS_2/AOCF对大肠杆菌的抗菌能力与0.8万单位的青霉素相当,而0.10g的nano-NiS_2/AOCF对枯草芽孢杆菌的抗菌能力与0.5万单位的青霉素相当。

The nano-nickel sulfide/amido, xime composite fiber （nano-NiSz/AOCF） was prepared using NiS2 nanocrystals and amidoxim-chelated polyacrylonitrile fibers. The composite fiber was characterized by SEM and EDX, demonstrating that NiS2 nanocrystals were deposited uniformly on the surface of the chelating polyacrylonitrile fiber. The antibacterial properties of the composite fibe.r against escherichia coli and bacillus subtilis were investigated. The results indicate that the antibacterial ability of 0. 18 g nano-Ag2 S / AOCF is approximate to 0.8 million units of penicillin to escherichia coli, while 0.10 g nano-Ag2S/AOCF is approximate to 0.5 million units of penicillin to bacillus subtilis.
