Abstract:
A process comprising:(a) producing a solution of an organic solvent and water; (b) contacting a surface of a solid substrate, which surface has reactive moieties thereon, with the solution and a derivatizing composition comprising a first silane, R1â€”Si(RLRXRY) and a second silane, R2â€”(L)nâ€”Si(RLRXRY), so that â€”Siâ€”R1 groups and â€”Siâ€”(L)nâ€”R2 groups become covalently coupled to the surface, wherein the RL moieties, which may be identical or different, are leaving groups, RX and RY are independently lower alkyl or leaving groups, R1 is a chemically inert moiety that lowers the surface energy of the substrate, n is 0 or 1, L is a linking group, and R2 is either a functional group enabling covalent binding of a molecular moiety or a modifiable group that may be converted to such a functional group.
