Abstract
The invention relates to a process for modifying an inorganic substrate, directed toward giving it antimicrobial properties, said process consisting in grafting in one or more steps onto a surface of said substrate groups with intrinsic antimicrobial properties or groups capable of releasing species with antimicrobial properties. The grafting is performed by means of an organophosphorus coupling agent.A subject of the invention is similarly a substrate obtained by this process, as well as diverse uses of such a substrate.
