Ion-selective membranes, a method for their preparation, use of the ion-selective membranes and devices, which are provided with the ion-selective membranes

摘要

PROBLEM TO BE SOLVED: To provide an ionic membrane or the like having uniform thickness and enough mechanical strength, hardly causing any pinhole and crack during membrane production and handling. ;SOLUTION: This ionic membrane formed out of an ionic membrane-forming component composed of a cationic polymer and/or anionic polymer component(s) and a matrix component, and a fabric-like support, is characterized in that each of the ionic polymer component is a granular polymer with a mean particle size of 0.01-10 μm and the fabric-like support has a network structure.;COPYRIGHT: (C)2000,JPO
