采用全模式光纤x射线衍射细化研究了三种不同热处理历史的聚对苯二甲酸乙酯纤维样品的晶体结构和形貌。用四圆衍射仪采集了整个二维空间的衍射数据。提出了一种迭代傅里叶滤波方法来分离晶体衍射和背景散射。发现组织和形貌都依赖于热处理。纤维的某些性能可以用晶体结构和晶体形态的差异来解释。
Full-pattern fiber X-ray diffraction refinement has been used to study the structure and morphology of the crystallites of three poly(ethylene terephthalate) fiber samples with different heat treatment history. Diffraction data over the whole two-dimensional space were collected with a four-circle diffractometer. An iterative Fourier filter method is developed to separate the crystalline diffraction from the background scattering. Both the structure and morphology are found to be dependent on the heat treatment. Some properties of the fibers can be explained by the difference in the crystal structure and morphology of crystallites.
