ION CONDUCTIVE POLYMER COMPOSITION, METHOD FOR PRODUCING THE SAME, FILM CONTAINING THE ION CONDUCTIVE POLYMER COMPOSITION, AND ELECTROCHEMICAL DEVICE USING THE FILM

摘要

Disclosed is a novel ion conductive polymer composition which is improved in ion conductivity and usable under high temperature low humidity conditions. Specifically disclosed is an ion conductive polymer composition obtained by mixing or combining a polymer compound (for example, a cation-exchange resin) and a metal oxide compound containing an acidic group. In this composition, the acidic group and the metal oxide compound are preferably bound by an organic group, and a compound represented by the following general formula: {(R¹O)_aX(R²Y)_b} is preferable as the metal oxide compound. The metal element in the metal oxide compound preferably contains silicon, titanium, aluminum or boron. The acidic group is preferably a sulfonic acid group, a phosphonic acid group or a carboxylic acid group.
