A versatile route for surface modification of carbon, metals and semi-conductors by diazonium salt-initiated photopolymerization

► Versatile method of surface-confined photopolymerization using grafted initiators. ► Initiators derive from electroreduction of diazonium salts. ► Application of the process to carbon, metals, alloys and semi-conductors. ► Polymer grafts have controlled chemical structure and wettability. ► Good adhesion in paint removal solvents, particularly for crosslinked polymers.
