多嵌段聚氨酯形态学结构是决定其力学性质和使用性能的主要因素之一。随着聚氨酯工业中反应注射成型(RIM)工艺的发展,形态学研究的重要性更趋突出。透射电镜(TEM)是研究聚氨酯形态学结构的重要物理仪器之一,前人已经做过许多工作,但对TEM照片的分析存在着相当大的
The multi-block polyurethane morphological structure is one of the main factors that determine its mechanical properties and performance. With the development of reactive injection molding (RIM) processes in the polyurethane industry, the importance of morphological studies becomes more apparent. Transmission electron microscopy (TEM) is one of the most important physical instruments for studying the morphological structure of polyurethane. Much work has been done before, but the analysis of TEM images is quite large
