摘要:
The invention provides a material coated with an organic film which exhibits excellent corrosion resistance and lacquer adhesion. The invention includes an electroconductive substrate coated with an electrolytically polymerized coating film containing chromium. Particularly, a zinc-type plated steel sheet coated with an electrolytically polymerized coating film containing chromium in accordance with the invention is well suited for application in vehicle bodies. The invention further provides a method of making a material coated with an organic film which involves forming organic coating material containing chromium on an electroconductive substrate acting as an electrode by electrolytically polymerizing an organic monomer in an electrolyte solution containing chromium. The method provides a monolithic composite structure comprising chromium compounds and an organic coating film, and avoid the problems associated with passivation after chromium plating of steel. The method of the invention can also reduce processing by two-thirds in relation to conventional methods.

L'invention est relative à un procédé de dépôt par électropolymérisation d'un film d'un matériau composite sur une surface conductrice d'électricité suivant lequel on fait usage d'un mélange comprenant (a) un monomère, (b) une substance formant un agent dopant, (c) un électrolyte-support et (d) un solvant, on soumet ce mélange à une électrolyse et on polarise la cathode ou anode à un potentiel situé dans la zone correspondant au transfert électronique entre la surface métallique et le monomère. On forme à partir du mélange précité, avant l'électrolyse, une solution dans laquelle la substance susdite est présente soit à l'état d'anion, de cation, de molécule, de préférence de molécule organique, et/ou de complexe non dissocié en ions.
摘要:
Disclosed is a method of producing a conductive polymer composite comprising a resin layer and a conductive polymer layer formed on the resin layer, which comprises the steps of dissolving, in a monomer component (a) which is polymerizable without condensation reaction, a monomer component (b) capable of undergoing electrolytic polymerization to give at least one conductive polymer and an electrolyte (c), introducing the resulting solution into an electrolytic polymerization cell, applying a direct current voltage across the cell to electrolytically polymerize the component (b) to thereby provide the conductive polymer layer, and thereafter subjecting the component (a) to polymerization in the cell to provide the resin layer.
摘要:
The invention relates to a process for uniformly incorporating powders into polymer layers. In the process the polymer layer is formed from a monomer solution on an electrically conductive substrate by means of electrolysis, while simultaneously or prior thereto, under influence of an applied force, the powder particles insoluble in the monomer solution are passed uniformly from the monomer solution to the electrically conductive substrate and subsequently fixed there.
