A template pattern with alternating poly (4-vinylpyridine) (P4VP) /poly (vinyl alcohol) (PVA) lamellae was fabricated upon a microporous poly (vinyl chloride) (PVC) membrane by casting of poly [4-vinylpyridine (4VP) -g-vinyl alcohol (VA)] graft copolymer. After a treatment of both binding of microporous membrane with graft copolymer and domain fixing of the PVA matrix, a dilute solution of poly [acrylic acid (AA) -benzyl N,N-diomethyldi-thiocarbamate (DMTC)] /P4VP or poly [sodium p-stirenesulfonate (SSS) -DMTC] /P4VP binary blend was cast on this template surface. Two types of weak acid/strong base or strong acid/strong base microdomains formed by epitaxial growth were oriented perpendicularly to the membrane surface. After the chemical treatments : introduction of the charge and domain fixing of ion exchange regions, two types of such mosaic microdomains could be constructed on a microporous membrane. We studied the transport behaviors of organic and inorganic solutes through charged mosaic composite membranes. The permeability of inorganic electrolyte, such as Kcl was about 20-fold compared to those of organic nonelectrolytes, such as glucose and sucrose.L-Phenylalanine exhibits a low value of permeability at the pH of its isoelectric point.

通过浇铸聚[4-乙烯基吡啶（4VP）]，在微孔聚（氯乙烯）（PVC）膜上制造具有交替聚（4-乙烯基吡啶）（P4VP）/聚（乙烯醇）（PVA）片层的模板图案 - g-乙烯醇(VA)]接枝共聚物。经过微孔膜与接枝共聚物的结合和PVA基体的域固定处理后，聚[丙烯酸(AA)-N,N-二甲基二硫代氨基甲酸苄酯(DMTC)]/P4VP或聚[钠]的稀溶液对苯乙烯磺酸盐(SSS)-DMTC]/P4VP二元共混物浇铸在该模板表面上。通过外延生长形成的两种类型的弱酸/强碱或强酸/强碱微区垂直于膜表面取向。经过化学处理：引入电荷和离子交换区域的域固定后，可以在微孔膜上构建两种类型的马赛克微域。我们研究了有机和无机溶质通过带电镶嵌复合膜的传输行为。无机电解质（例如Kcl）的渗透性约为有机非电解质（例如葡萄糖和蔗糖）的20倍。L-苯丙氨酸在其等电点的pH值下表现出较低的渗透性值。
