摘要

The microstructure of the polyacrylonitrile(PAN)-stabilized fibers was investigated by X-ray diffrac-tion (XRD), scanning electron microscope (SEM), transmis-sion electron microscope (TEM), and high-resolutiontransmission electron microscope (HRTEM). XRD analysisindicated that the chemical reactions sped up notablywhen temperature was above 250°C. The crosssection SEMimage of the stabilized fibers presented concentric multi-layer morphology. TEM images showed that the lamellar-like skin was compact and the core was disorderly andloose. The vermiculate-like crystallites in the precursor
