摘　　要：通过X射线二维衍射图像和 2θ扫描法对四种不同的国内外聚丙烯腈原丝进行了结构表征 ,探讨了不同PAN纤维在微观结构上的差异 ,为深入分析PAN原丝的序态结构和了解其结构性能关系。Microstructural features of four PAN fibers were investigated by wide angle X ray diffraction(WAXD) including both two dimensional and 2 θ scan examinations. The difference in the microstructure among such samples was studied. The results provide more details for understanding their morphological structure and finding out the relationship between the structure and the property of PAN precursor.
