Claim:
1. A method for making an ion exchange membrane comprising polymerizing an ionic monomer, and optionally another, second compound, in the presence of inorganic particles to form the ion exchange membrane, the monomer or second compound linking to the inorganic particles by a physical or chemical bond, wherein the monomer or second compound links to the inorganic particles by a C—O or N—O chemical bond, hydrogen bonding or π-π stacking, and wherein the monomer or second compound is selected from the group consisting of a) ethylenic monomers, b) polyepoxides, c) N-vinyl caprolactam, d) glycidyl methacrylate and e) a reaction product of dimethylaminopropylmethacrylamide (DMAPMA) and 1,4-cyclohexanedimethanol diglycidyl ether (CHDMDGE).
