气体分离复合膜(1)。酸性气体分离复合膜的制造方法和酸性气体分离膜组件
摘要：
本发明制造酸性气体分离性优异、涂布适合性优良的酸性气体分离用涂布液以及使用了该涂布液制造酸性气体分离性优异的酸性气体分离复合膜。准备将聚乙烯醇缩醛化合物、酸性气体载体以及除氢氧根离子、羧基离子、碳酸根离子和碳酸氢根离子以外的至少一种阴离子分散或溶解于水中而形成的酸性气体分离用涂布液，该聚乙烯醇缩醛化合物通过使由聚乙烯醇形成的聚合物嵌段与由聚丙烯酸盐形成的聚合物嵌段经由连接基团键合而成的嵌段共聚物利用缩醛键进行交联而形成，在至少一个表面为疏水性的多孔质支撑体(2)的疏水性表面上将该酸性气体分离用涂布液涂布成膜，制造在多孔质支撑体(2)上具备酸性气体分离促进输送膜(3)的酸性
摘要（英）：

To produce a coating liquid for acid gas separation, the coating liquid having excellent acid gas separating properties and excellent coating appropriateness, and to produce an acid gas separation composite membrane having excellent acid gas separating properties by using the same. A solution is to produce an acid gas separation composite membrane (1) provided with an acid gas separation facilitated membrane (3) on a porous support (2), including; arranging of a coating liquid for acid gas separation formed through dispersing or dissolving into water a polyvinyl acetal compound formed through crosslinking, by an acetal bond, block copolymers formed through bonding of a polymer block formed of polyvinyl alcohol and a polymer block formed of polyacrylate through a linking group, an acid gas carrier and at least one kind of anion other than hydroxide ion, carboxyl ion, carbonate ion and bicarbonate ion, and coating of the coating liquid for acid gas separation onto a hydrophobic surface of the porous support (2) having hydrophobicity at least on one surface to form the acid gas separation facilitated transport membrane (3) thereon.
