Abstract
A method for preparing a polymeric material doped with at least one first metal element and at least one second metal element, including: a) copolymerization of a first monomer containing a first metal element and of a second monomer containing a chelating group of a second metal element, to obtain a polymeric material containing (i) recurrent units deriving from the polymerization of the first monomer, the recurrent units containing the first metal element and (ii) recurrent units deriving from the polymerization of the second monomer, the recurrent units containing chelating groups of a second metal element, and when the first metal element is different from the second metal element, b) contacting the material from a) with a solution containing the second metal element, in return for which the second metal element is complexed with the chelating groups, where b) is optional when the first and second metal element are identical.
