PARTICULES INORGANIQUES ORGANOMODIFIEES, PROCEDE DE PREPARATION DE CELLES-CI ET UTILISATION DANS UN MATERIAU COMPOSITE POUR MEMBRANE DE PILE A COMBUSTIBLE.

摘要

The invention relates to proton-conducting composites comprising a polymer matrix within which inorganic particles are dispersed, grafted to the surface of which particles are polymers comprising repeat units that comprise at least one acid proton-exchange group, optionally in the form of salts, or a precursor group of said acid group, said particles being chosen from particles of zeolites, of zirconium phosphates or phosphonates, or of oxides. Application to the field of fuel cells.
