Abstract
The present invention concerns a method for preparing an organic copolymer film on electrically conductive or semi-conductive surfaces in two steps. The first step includes electrolysis of an electrolytic solution containing an adhesion primer, in contact with a surface. The second step corresponds to the reaction, at the surface obtained previously, of a solution containing the following species: a protic solvent, and a “radically polymerizable” monomer. The polymerizable monomer is solubilized in micellar form. The surfaces obtained with the use of this method, and their applications apply to preparation of microelectronic components, biomedical devices or screening kits, as well as kits for preparing an organic copolymer film on an electrically conductive or semi-conductive surface.
