METHOD FOR ELECTROPOLYMERIZATION DEPOSITION OF ORGANIC THIN FILMS ON SURFACES CONDUCTING ELECTRICITY, ESPECIALLY ON METALLIC SURFACES, AND THIN FILMS THUS OBTAINED

摘要

The object of the present invention is to provide a process for the electropolymerization of organic thin films on electrically conductive surfaces, particularly on metal surfaces. This process consists of: / p P AA PREPARE A SOLUTION HAVING A WATER CONTENT NOT EXCEEDING 10M1 INCLUDING: / P P - A MONOMER CONSISTING OF AN ORGANIC MOLECULE COMPRISING A TERMINAL ETHYLENIC BOND CONJUGATED WITH ELECTROATTRACTIVE GROUPING, / P A SUPPORT ELECTROLYTE CONSISTING OF A QUATERNARY AMMONIUM PERCHLORATE, AND AN APROTIC ORGANIC SOLVENT THAT DOES NOT GIVE ANY PARASITIC REACTION TO THIS MONOMER; AND / P P BA ELECTROLYSER SAME SOLUTION IN AN ELECTROLYSIS CELL USING AS CATHODE THE CONDUCTIVE SURFACE TO REVETIZE AND POLARIZING THIS CATHODE TO A POTENTIAL LOCATED IN THE AREA CORRESPONDING TO DIRECT ELECTRONIC TRANSFER BETWEEN THE METAL SURFACE THAT PLAYS THE ROLE OF CATHODE AND THE MONOMER, AND OF A VALUE MORE NEGATIVE THAN THAT CORRESPONDING TO THE PIC OF INHIBITION OF THE CATHODIC REACTION OF THE MONOMER. / P P APPLICATION TO THE PRODUCTION OF ELECTRONIC COMPONENTS OR INTEGRATED OPTICAL DEVICES. / P
