摘要
以高密度聚乙烯(HDPE)和邻苯二甲酸二丁酯(DBP)作为膜材料和稀释剂,采用热致相分离法(TIPS)制备了用于电池隔膜材料的微孔膜。通过对HDPE/DBP体系的相分离过程进行研究,绘制了HDPE/DBP体系的相图。用扫描电子显微镜(SEM)研究了二元体系的相分离过程及聚合物浓度、冷却速率对膜断面微观结构的影响。
Microporous membrane for battery separators were prepared with HDPE and DBP by thermally induced phase separation (TIPS) method .The phase diagrams of HDPE with DBP were determined by researching the process of phase separation of HDPE with DBP. The effects of phase separation process, polymer concentration and cooling rate on membrane cross-section microstructures were characterized by SEM.
