  • Surface modification of solid supports through the thermal decomposition and functionalization of silanes
    Patent number: 6444326
    Abstract: Method of modifying the surface properties of a substrate by depositing a coating of hydrogenated amorphous silicon on the surface of the substrate and functionalizing the coated substrate by exposing the substrate to a binding reagent having at least one unsaturated hydrocarbon group under pressure and elevated temperature for an effective length of time. The hydrogenated amorphous silicon coating is deposited by exposing the substrate to silicon hydride gas under pressure and elevated temperature for an effective length of time.
