二次膜射流乳化法制备单分散乳液模板的研究
DOI: 10.3969/j.issn.1671-7627.2006.01.004
Keywords: 膜乳化,乳液模板,射流
Abstract:
乳液模板法是一种制备高度有序多孔材料的重要方法,而膜乳化法则是一种新型的通过膜结构制备乳液的方法.文中提出了一种采用二次膜射流乳化制备单分散乳液模板的方法,平均孔径为0.16μm和1.5μm的陶瓷膜分别被作为两次乳化的乳化介质.采用异辛烷/甲酰胺体系为研究对象,嵌段高分子聚(乙二醇)聚(丙二醇)聚(乙二醇)作为乳化剂.实验表明一级膜乳化过程的通量为75.4l/(m2·h),二级膜乳化过程的通量可达到169.9l/(m2·h).所得单分散乳液模板的平均粒径为1.8μm,且在10h内能保持较好的稳定性.
