以聚丙烯腈（ＰＡＮ）为膜材料考察了铸膜液浓度、不同添加剂、不同硅橡胶对膜性能的影响制成了ＰＡＮ基膜和ＰＡＮ复合膜利用电镜考察了ＰＡＮ基膜的形态和结构将ＰＡＮ基膜与ＰＡＮ复合膜分别浸泡在７种溶剂中２００～１３２０ｈ，观察膜性能及膜失重变化测定复合膜对有机蒸汽的分离性能，实验结果表明，ＰＡＮ－ＳＲ复合膜适用于从空气中分离有机蒸汽
The effect of casting solution concentration, different additives and different silicone rubbers on the properties of the films was investigated by using polyacrylonitrile (PAN) as the membrane material. PAN base and PAN composite films were prepared. The morphology and Structure The PAN-based and PAN-composite membranes were soaked in seven solvents for 200 ~ 1320h respectively, and the changes of film properties and weight loss were observed The separation performance of the composite film on organic vapors was determined. The experimental results show that the PAN-SR composite film is suitable for Separation of organic vapors from the air
