摘要：There is provided a multilayered charge-mosaic membrane having a poroussupporting layer (A), a porous intermediate layer (B) and a charge-mosaic layer (C),

wherein the porous supporting layer (A), the porous intermediate layer (B) and thecharge-mosaic layer (C) are located in this order; the porous supporting layer (A) and/orthe porous intermediate layer (B) are made of a fiber layer containing hydrophilic fibers; athickness of the porous intermediate layer (B) is 0.1 to 100 μm; a porosity of the poroussupporting layer (A) is larger than a porosity of the porous intermediate layer (B); thecationic and/or the anionic polymers constituting the charge-mosaic layer (C) is apolyvinyl alcohol having an ionic group. Thus, there is provided a multilayered charge-mosaic membrane having a large salt permeation flux and excellent mechanical strength.
