| 摘 要： | 采用原位聚合法,在吡咯的水性溶液中可制备具有良好导电性的聚毗咯／尼龙6复合纤维。文章探讨了反应过程中各种因素对所制得的聚吡咯／尼龙6复合导电纤维导电性的影响。结果表明,FeCl3是一种较为有效的氧化剂。采用吡咯单体浓度为0．05 mol/L、氧化剂与吡咯的初始摩尔比为2．3、反应温度为20℃,反应时间为3 h的反应条件,可制得具有较好导电性的复合纤维。电镜照片显示,复合导电纤维呈现皮芯结构,聚吡咯主要集中在皮层,形成导电通道。

| Abstract: | Polypyrrole/nylon-6 composite fiber can be prepared by in-situ polymerization in pyrrole-aqueous solution . The effects of various parameters during the processing on the fiber conductivity were investigated in the paper. The results show that FeCl3·6H2O can be used as an effective oxidant and the optimal reaction conditions for excellent conducting performance are as follow: pyrrole concentration 0.05 mol/L, the initial mole ratio of oxidant/pyrrole 2.3, reaction temperature 20 ℃ and reaction time 3 h. The SEM photos show that the composite fiber presents skin-core structure and polypyrrole concentrates on the skin which forms conducting passage. |
