Abstract

A method of conferring modified properties, e.g. modified physical and/or biochemical properties, to a metallic substrate surface, including at least two steps being (i) a first step including at least exposing the substrate surface to a hetero-bifunctional anchoring molecule carrying at least a silane group and at least a Agroup, the Agroup being optionally introduced within the anchoring molecule via a preliminary functionalizing step, and (ii) a second step of exposing the substrate surface to a polymer carrying at least three groups Acapable of reacting with Ain a thiol-ene reaction, the number average molecular weight of the polymer being greater than 1 000 g/mol.
