| Abstract
| - This paper describes two different methods, based on the electrochemical reduction ofdiazonium salts, for the strong binding of polymers to an iron surface. The first methodinvolves the electrochemical reduction, on an iron electrode, of the diazonium salt of4-aminobenzophenone. This permits the covalent attachment of 4-benzoylphenyl moietieson the surface. Polystyrene (PS) is then deposited on the modified iron surface and can becovalently bonded to the 4-benzoylphenyl groups under irradiation. Another method involvesthe attachment of carboxyphenyl groups to the iron surface by reduction of the diazoniumsalt of 4-aminobenzoic acid and the further attachment of poly(1,2-propanediyl fumarate)to the phenylcarboxylate functions through ionic bonds with Mg2+ ions. The barrier propertiesof the polymeric films are characterized by electrochemistry and by the protection theyprovide against corrosion.
