一种用X-衍射测定PET纤维非晶取向度的简易方法

A Simple Method for Determining PET Fiber's Orientation Factor of Amorphous Region with WAXD

在传统ＷＡＸＤ法的以一系列方位角下径向扫描曲线分峰计算ＰＥＴ纤维非晶取向度的基础上，提出利用２θ＝１７．５°的方位角扫描曲线一次分峰即可求得ＰＥＴ纤维非晶取向度的方法，该方法的优点是结晶峰干扰小，易于分离，计算时拟合误差大大减小。

Based on the traditional WAXD method determining orientation factor of amorphous region by a series of profiles of azimuthal scaning, a new method to get the PET fiber's orientation factor of amorphous region was suggested, which was based on a single azimuthal scan at 2θ=17. 5° with the advantages of easiness and accuracy.
