| 摘 要： | 铸膜液的溶剂体系（溶剂和非溶剂）对不对称膜形态的形成有重要作用。为了探索溶剂和透气性间的关系，本文考虑到了制备ＢＣＡ梯度密度不对称膜的各种溶剂的一系列物理参数，得到了一些定性结果，并指出了更全面、明确、解释两者关系的研究方向。

| Abstract: | Solvent system including solvent and nonsolvent in membrane casting solution plays an important role for making the morphology of asymmetric membrane. To find out the relationship between solvent and gas permeability, in this paper series of physical parameter of solvents have ho considered in preparation of BCA graded density asymmetric membranes. Some qualitative results have been obtained. Besides, further studies are showed to explain the relationship more inclusive and decisive. |
