Abstract
The present invention relates to a process for grafting and growing a conductive organic film on(to) an electrically conductive or semiconductive surface in which the grafting and growing of the film are performed simultaneously by electro-reduction of a diazonium salt that is a precursor of the said film on(to) the said surface cathodically polarized at a potential greater than or equal, in absolute value, to the electro-reduction potential of the diazonium salt relative to a reference electrode.The invention finds an application especially in the protection of surfaces, the manufacture of localized conductive coatings, of chemical sensors in the fields of chemistry and molecular biology, the manufacture of biomedical equipment, etc.
