摘　　要：以静电纺丝技术制备出尼龙6(PA6)纳米纤维,并以该纳米纤维为模板,采用原位聚合法进行对甲苯磺酸(TSA)掺杂的聚苯胺(PANI)的合成,制备PANI-TSA/PA6核壳结构复合纳米纤维。应用傅里叶红外变换光谱测试仪(FT-IR)、场发射扫描电子显微镜(FE-SEM)对纤维的结构进行了表征;利用热重测试仪(TG)对纤维的热性能进行了表征。结果表明,采用该方法制备出了以TSA-PANI为壳、PA6为核的复合纳米纤维,且纤维形貌规整均匀,热性能优良。PANI TSA/PA6 core-shell nanofibers were prepared via the electrospinning process with a nylon-6/for mic acid polymer solution and then chemical polymerization of PANI doped with p-toluene sulfonic acid on the surface of the nylon 6 nanofibers. The structure and thermal stability of nylon-6 nanofibers and PANI-TSA/nylon-6 composite nanofibers were investigated by SEM, TGand rotating viscometer. All the results showed that, nanofibers with PANI-TSA shell and PA6 core had been prepared successfully,which showed good performance of structure and thermal stability.
