| description | A charge mosaic membrane having excellent selective permeability comprises a cationic polymer component, an anionic polymer component and a matrix component. Both of the cationic polymer component and the anionic polymer component are crosslinked particulate polymers. The matrix component is at least one polymer selected from a polysulfone resin, a polyarylate resin, a polyamide resin, a polyimide resin, a polyamideimide resin, a polyurethane resin, a fluorinated resin or a silicone resin. The charge mosaic membrane can be easily produced by conducting formation of the membrane by using a composition in which the cationic polymer component and the anionic polymer component are both dispersed in a solution of the matrix component in an organic solvent. |
