Hollow fiber type pervaporation membranes were successfully prepared by plasma-graft filling polymerization. The membrane is composed of two different polymers ; a porous substrate which can suppress membrane swelling, and a grafted polymer whic forms in the pores of the substrate and exhibits selectivity due to its solubility. Specifically, a porous high-density polyethylene membrane and poly (methylacrylate) were emlployed as the porous substrate and grafted polymer, respectively. Through this technique, the grafted polymer was formed in the pores of the substrate, and the thickness of the grafted layr was around 20mum. Pervaporation separation of benzene/cyclohexane or chloroform/carbontetrachloride were performed with the membranes. The mechanical strength of hollow-fiber substrate was weaker than flat sheet membranes, and the pervaporation selectivity was lower than the membranes. Crosslinking and copolymerization technique were employed to reduce the membrane swelling. Both method allowed us to obtain higher selectivity although permeability was sacrificed. Using these method, we obtained a hollow-fiber membranes having the same level of separation performances that the flat sheet membrane showed.

通过血浆填充聚合成功制备了空心纤维类型的杂化膜。膜由两个不同的聚合物组成。可以抑制膜肿胀的多孔底物，并在基板的毛孔中形成接枝的聚合物，并由于其溶解度而表现出选择性。具体而言，分别将多孔的高密度聚乙烯膜和聚丙烯酸酯和聚丙烯酸酯分别作为多孔底物和接枝聚合物。通过该技术，在底物的毛孔中形成移植聚合物，移植的Layr的厚度约为20M。用膜进行了苯/环己烷或氯仿/氯仿/氯仿/氯仿的透露分离。空心纤维底物的机械强度比平板膜弱，并且透化选择性低于膜。采用交联和共聚技术来减少膜肿胀。两种方法都使我们获得了更高的选择性，尽管牺牲了渗透性。使用这些方法，我们获得了一个空心纤维膜，其分离性能水平与平板膜所显示的相同水平。
