Beschreibung
Zusammenfassung:	The invention relates to a method for functionalization of inorganic particles by polymers comprising at least one recurrent unit bearing at least one proton exchange group comprising the following steps: a) a step for functionalization of inorganic particles by an anionic polymerization termination agent comprising at least one group capable of being bound to the surface of said particles; b) a step for anionic polymerization of at least one monomer bearing at least one precursor group of a proton exchange group; c) a step for putting the particles obtained in step a) in contact with the polymers obtained in step b), in return for which the obtained particles are particles functionalized by said polymers by reaction between a reactive end of said polymeric polymers and at least one group of the aforementioned termination agent; and d) a step for transformation of the precursor group(s) of said proton exchange group(s).
