Method of preparing acrylic ion-transfer membranes

摘要

Ion exchange resins can be prepared by co-polymerizing a major amount (>88 mol %) of non-ionic acrylic monomer, such as methyl methacrylate, with a minor amount (3 to 12 mol %) of an ionogenous monomer such as methacrylamidopropyltrimethylammonium chloride or 2-acrylamido-2-methyl propane sulfonic acid. The resultant anion-conductive or cation conductive membranes exhibit low swelling in water and high ion-transference numbers. The membranes may be applied as coatings on neural prosthesis electrodes.
