Abstract:
1. A method for preparing a composite material comprising a polymeric matrix and a filler consisting of ion exchange inorganic particles comprising a step for synthesis in situ of said particles within the polymeric matrix, wherein the step for synthesis in situ is carried out with the sol-gel method comprising the following operations: an operation for putting the constitutive polymer(s) of the matrix in contact with one or more precursors of the inorganic particles, said precursor(s) fitting the following formula: wherein: M is a metal element or a metalloid element; X is a hydrolyzable chemical group; R is a chemical exchange group or a precursor group of an ion exchange chemical group; y corresponds to the valence of the element M; and n is an integer ranging from 0 to (y-1);
