利用静电纺丝技术,以聚丙烯腈(PAN)和苯胺(ANI)为前驱物,用过硫酸胺(APS)溶液在低温下缓慢氧化聚合,制备了PAN/PANI复合纳米纤维,直径约500 nm.通过扫描电子显微镜(SEM)、红外光谱(FTIR)、X射线衍射(XRD)和激光拉曼(RAMAN)光谱仪等测试手段对材料的形貌和结构进行了表征.探讨了材料制备过程中影响纤维形貌、尺寸、均匀度的因素和PANI含量对复合纤维导电性能的影响,结果表明,PAN浓度、ANI的加入量和电压是影响纤维特性的主要因素;PANI在PAN基体中呈纳米尺寸分布,复合纳米纤维具有良好的导电性能,导电率可达10-2S/cm.
PAN / PANI composite nanofibers were prepared by electrospinning using polyaniline (PAN) and aniline (ANI) as precursors and slowly oxidized and polymerized with ammonium persulfate (APS) solution at a low temperature of 500 nm The morphology and structure of the material were characterized by scanning electron microscopy (SEM), infrared spectroscopy (FTIR), X-ray diffraction (XRD) and laser raman spectroscopy (RAMAN) The results showed that the concentration of PAN, the amount of ANI and the voltage were the main factors affecting the fiber properties. The PANI exhibited nanosize distribution in PAN matrix , Composite nanofibers with good conductivity, conductivity up to 10-2S / cm.
