Abstract:
1. A process for the formation of a polymer film on a cathodic electrically conducting or semiconducting surface by electrografting, comprising: a) preparing an electrolytic solution consisting of one electropolymerizable monomer and one source of protons which is chosen from compounds which are Bronsted acids in the said electrolytic solution, the said Bronsted acids being chosen from water and weak acids, and the said source of protons being present in an amount of between 50 and 10 000 ppm with respect to the total amount of the constituents of the said electrolytic solution, and optionally at least one solvent; and b) electrolysing the said solution in an electrolysis cell by using the conducting or semiconducting surface to be covered as working electrode and at least one counter electrode, to result, by electroreduction or electro-oxidation of the said solution, in the formation of an electrografted polymer film on the said surface via an anionic polymerization process.
