Abstract :	[en] An original way to synthesize nanostructured materials is the use of new structuring agents constituted of induced and reversible micelles of Double Hydrophilic Block Copolymers (DHBC). The present paper aims at showing that induced micelles can be obtained by complexation between a PAA-b-PAMPEO (DHBC) polymer containing a comb-type neutral block and a polyamine, that the micellization process is reversible as a function of the pH and finally, that the obtained polyion complex micelles can be successfully used in the preparation of well organized mesostructured silica materials.
