Proton conducting polymer, and application thereof as electrolyte in electrochemical devices

摘要

This invention has as its subject a basic organo-mineral proton conducting polymer, produced by copolymerization of three precursors: a precursor based upon a trialkoxysilane, onto which a methane sulphonamide group is grafted by means of an alkyl or aryl link, a "deprotonizing" precursor based upon a trialkoxysilane, onto which is grafted a group derived from a nitrogenous base, preferably an imidazoline group, by means of an alkyl or aryl link, a "plasticizing" and solvating precursor, having at least one urea group which is the product of a reaction between a primary mono-, di- or triamine D and a trialkoxysilane E onto which an isocyanate group has been grafted by means of an alkyl link.
