利用静电纺丝法制备了含有一定质量FeCl3的聚丙烯腈/氯化铁(PAN/FeCl3)复合纳米纤维,并在表面引发聚合吡咯。利用扫描电子显微镜(SEM)对纤维的整体形貌进行表征;应用傅里叶变换红外光谱(FT-IR)对纤维的化学组成进行分析;同时借助热重(TG)分析了表面引发聚合吡咯后对复合纳米纤维热性能的影响。结果表明:采用该方法制备出了以PAN-FeCl3为芯层,聚吡咯(PPy)为皮层的复合纳米纤维,且纤维表面形貌规整均匀,热性能优良。
Polyacrylonitrile / ferric chloride (PAN / FeCl3) composite nanofibers containing certain amount of FeCl3 were prepared by electrospinning method and polymerized pyrrole was initiated on the surface. The morphology of the fiber was characterized by scanning electron microscopy (SEM). The chemical composition of the fiber was analyzed by Fourier transform infrared spectroscopy (FT-IR). At the same time, the pyrolytic (TG) Effect on thermal properties of composite nanofibers. The results show that the composite nanofibers with PAN-FeCl3 as the core and PPy as the cortex are prepared by this method. The surface morphology of the fibers is uniform and the thermal properties are excellent.
