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.

采用等离子体接枝填充聚合法成功制备了中空纤维型渗透汽化膜。该膜由两种不同的聚合物组成：可以抑制膜溶胀的多孔基材和在基材的孔中形成并由于其溶解性而表现出选择性的接枝聚合物。具体而言，多孔高密度聚乙烯膜和聚（甲基丙烯酸酯）emlployed作为多孔基板和接枝聚合物，分别。通过这种技术，接枝聚合物在基底的孔中形成，并且接枝层的厚度为约20 μ m。用该膜对苯/环己烷和氯仿/四氯化碳进行了渗透汽化分离。中空纤维膜的机械强度比平板膜弱，渗透汽化选择性比平板膜低。采用交联和共聚技术来降低膜的溶胀。这两种方法使我们获得更高的选择性，虽然牺牲了渗透性。利用这些方法，我们获得了中空纤维膜，其具有与平片膜相同的分离性能。
