摘要
用聚砜和添加剂的二甲基甲酰胺溶液制备了共混膜．并在室温下测定这些膜对二氧化碳 和氮气的透气性．实验表明，醋酸铜－聚砜共混膜具有较好的二氧化碳选择透过性．还讨论了制膜 条件对共混膜性能的影响．
Blend membranes were prepared by using casting solutions which consisted of polysulfone(PSF), dimethylformamide and addictives. Experiments measured the permeabilities of the membranes for carbon dioxide and nitrogen under room temperature. The results showed that Cu(Ac)2-PSP blend membrane presented better permselectivity for CO2 versus N2. Effects of preparing conditions on the blend membrane characteristics were also discussed.
