Avrami and Ozawa equations were used to analyze the experiment data in this study. Because the melting point of PBS is high and the mechanical properties are worse. In addition, the PTS is uncrystallized. Therefore, PBS and PTS were mixed to improve their properties. PBS containing 5wt% PTS can be able to reduce the crystallization performance, and make the polymer strength to enhance. Furthermore, the brittle fracture situation of PBS is also improved simultaneously.

本研究运用等温结晶分析使用的Avrami 方程式以及Ozawa 方程式，分析实验所得的数据，因为PBS 的熔点较高，机械性能较差，加上PTS 几乎不结晶的特性，因此将PBS 及PTS 以不同比例混掺的方式，对PBS 进行分析研究，结果发现，加入5wt% PTS的共聚酯能够明显的降低结晶性能，进而使聚合物的拉伸强度提高，同时脆性断裂的情况也得到改善。

Precision coating is a very important process in manufacturing of thin films. Among many coating techniques, slot coating may be the most promising in developing high precision coating process due to its versatility and controllability. Fundamentals of slot coating have been studied by many pioneer researchers. However, two topics: use of polymer additives and discrete operation remained relatively largely uninvestigated, especially in terms of their basic mechanisms. These two topics are studied in this thesis using theoretical analysis and experimental methods.
