    摘要： The invention concerns a method for forming a coating on conductive particles by grafting a polymer and/or a copolymer of the particles from a bath containing at least a monomer from which the polymer and/or copolymer is formed. The method consists of producing the grafting by electrochemical reduction of the monomer in an electrolytic solution, where at least a cathode and an anode are provided, and containing an aprotic solvent, a support electrolyte and the monomer(s) required for polymerizing or copolymerizing the coating, by suspending the particles and moving the solution so as to produce an intermittent contact between the particles and the cathode, and to form, by polymerization or copolymerization, the coating on the particles by applying an electric potential.
