【Abstract】 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.更多还原
