    摘要: The present invention relates to the field of surface coatings, said coatings being in the form of organic films. It relates more particularly to a method of forming copolymeric organic films by electrochemical grafting onto electrically conducting or semiconducting surfaces from aqueous electrolyte solutions containing at least one protic solvent, at least one radical polymerization initiator soluble in the protic solvent, at least one radical-polymerizable monomer, and at least one surfactant. The invention also relates to the surfaces obtained by implementing this method, to their applications, in particular for the preparation of microelectronic components, biomedical devices or screen kits, and also to the electrolyte solution employed during the method.

    摘要: The invention relates to a method of coating a simple or complex, conducting or semiconducting surface with an organic film using at least one precursor of said organic film. The invention is characterised in that the surface is coated with the organic film through the initiated electro-grafting of said at least one precursor onto the surface by performing at least one potential scanning on the surface such that, at every point of the surface, the maximum potential of each scanning of potentials, in absolute value and in relation to a reference electrode, is greater than or equal to the potential value (Vbloc) from which the curves of a graphic representation, expressing the quantity of electro-grafted precursor on a surface identical to said surface according to the number of potential scannings, all overlap and are independent of potential Vbloc.
