| 摘 要： | 采用原位聚合法制备了聚丙烯腈(PAN)-氧化石墨烯(GO)纳米复合物,并采用静电纺丝法制备了PAN及PAN-GO纳米复合物的电纺纤维。采用扫描电镜、傅里叶变换红外光谱、X射线衍射等研究了电纺纤维在恒温热稳定化过程中表面形貌、微晶结构、化学结构的变化,结果表明:恒温热处理后,纤维表面均较为光滑,GO的引入不仅能够加快热稳定化过程中环化反应的速度,而且能显著提高环化程度。

| Abstract: | Polyacrylonitrile (PAN)-graphene oxide (GO) nanocomposites were prepared by in-situ polymerization, PAN and PAN-GO fibers were then fabricated by electrospinning. Morphology and structure of the fibers stabilized at constant temperature were characterized by scanning electron microscopy, Fourier transform infrared spectroscopy and X-ray diffraction. The smooth surface was observed in stabilized fibers. The cyclization reaction of fiber was accelerated with the introduction of GO during stabilization, and meanwhile a considerable increase of the degree of cyclization was obtained in result fibers. |
