摘要(Abstract)：
利用聚丙烯腈(PAN)纤维为原料,经羟胺改性后得到具有螯合性能的偕胺肟纤维(AOCF),然后将AOCF浸渍于硫化铅(PbS)纳米溶胶中,利用物理吸附以及微粒表面与AOCF中的羟基和胺基的键合作用,合成了纳米PbS/AOCF复合纤维。分别对产物进行TEM、XRD、IR及AFM表征,结果表明:纤维上纳米PbS的粒径大小平均为30nm,呈规则的纳米球形,且分散性较好,均匀分布在纤维的表面。
The chelating fiber(AOCF) was prepared with the addition reaction of the polyacrylonitrile fiber (PAN)and hydroxylarnine. Then the chelating fiber was infused in lead sulfide nano-colloidal solutions. Nanometer lead sulfide/polyacrylonitrile fiber was synthesized by physical adsorption and chemical bond which occurred between particulate surface and hydroxy,amidocyanogen. TEM、XRD、IR and AFM were adopted for characterization of products. The results indicated that nanospheres of PbS on fiber with regular shape and PbS grain size is 30 nm. Nanometer lead sulfide dispersed well and even distributed on the fiber surface.
