The invention relates to a method for grafting an organic film onto an electically conductive or semiconductive surface by electro-reduction of a solution, wherein the solution comprises one diazonium salt and one monomer bearing at least one chain polymerizable functional group. During the electrolyzing process, at least one protocole consisting of an electrical polarization of the surface by applying a variable potential over at least a range of values which are more cathodic that the reduction or peak potential of all diazonium salts in said solution is applied.
The invention also relates to an electrically conducting or semiconducting surface obtained by implementing this method.
The invention further relates to electrolytic compositions.
本发明涉及一种通过电还原溶液将有机薄膜接枝到导电或半导电表面上的方法,其中溶液包括一种重氮盐和一种带有至少一种可链聚合官能团的单体。在电解过程中,至少有一个原极包括通过在至少一定范围内施加一个可变电位对表面进行电极化,该电位比所述溶液中所有重氮盐的还原电位或峰值电位的阴极性更强。
本发明还涉及通过实施该方法获得的导电或半导体表面。
本发明还涉及电解组合物。
