Abstract:
1. A method of modifying the surface of a metallic material to obtain a metallic material, wherein the surface of which is modified by bonding aromatic groups to the said surface, optionally substituted by functional groups, the nature of the bond between the surface and the aromatic groups that modify it being a carbon-metal bond of covalent type, comprising attaching an aromatic group to the surface of said material by electrochemical reduction of a diazonium salt containing this aromatic group, bringing the metallic material into contact with a solution of the diazonium salt in a solvent and by negatively polarizing the metallic material relative to an anode that is also in contact with the solution of the diazonium salt, and wherein the anode and the cathode are optionally separated from one another.
