A process of modifiying a solid's surface, comprising a first step of depositing hydrogenated armophous silicon on the surface by thermal decomposition at an elevated temperature of silicon hydride gas to form silane radicals which recombine to coat the surface with hydrogenated armophous silicon. A second step of surface funtionalization of the hydrogenated armophous silicon in the presence of a binding agent including hydrosilylation, disproportionation and radical quenching.
L'invention concerne un procédé permettant de modifier une surface de solide, qui consiste d'abord à déposer une couche de silicium amorphe hydrogéné sur la surface d'un support solide par l'intermédiaire de la décomposition thermique d'un gaz de silicium hybride, à une température élevée, afin de former des radicaux de silane qui se recombinent de façon à revêtir ladite surface avec du silicium amorphe hydrogéné; puis à fonctionnaliser la surface de la couche de silicium amorphe hydrogéné par exposition à agent de liaison notamment par l'intermédiaire de l'hydrosilylation, la dismutation, et la désactivation de radicaux libres.
