本文以聚偏氟乙烯（PSF）为膜材料,以二甲基乙酰胺（DMAc）为溶剂,以氯化锂（Licl）为添加剂,甲醇、乙醇和甘油分别为凝胶浴,通过浸没沉淀-相转化法制备了不同凝胶浴组成的微滤膜.用微滤膜膜评价装置测定了膜的纯水通量和对BSA的截留率.同时测量微滤膜的长宽及干湿重进行孔隙率的计算.考察了凝胶浴性质对膜结构和膜性能的影响,通过调控凝胶浴的组成,获得了具有性能较的PVDF膜,并对相转化成膜机理进行了分析.
In this paper,polyvinylidene fluoride (PSF) as the membrane material,to dimethylacetamide (DMAc) as solvent and lithium chloride (Licl) as additives,methanol,ethanol and glycerin bath gel,respectively,by immersion precipitation - prepared by phase inversion with different membrane composition of coagulation bath.Evaluation of microfiltration membrane device with a measured water flux and BSA rejection rate.Simultaneous measurement of membrane length and width and the porosity of wet and dry weight were calculated.Investigated the nature of coagulation bath on membrane structure and membrane properties,by regulating the composition of coagulation bath,access to the PVDF membrane with a performance than,and the formation mechanism of phase transformation were analyzed.
