Abstract

L'invention concerne une membrane composite dans laquelle un substrat poreux est imprégné d'une composition polymère contenant diverses combinaisons de α,β,β-trifluorostyrène, de α,β,β-trifluorostyrène substitué et d'unités monomères à base d'éthylène. Quand la composition polymère comporte des groupes échangeurs d'ions, les membranes composites obtenues sont utiles dans des applications électrochimiques, notamment comme électrolytes à membrane dans les cellules électrochimiques.
