INSTALLATION FOR CONDUCTIVE POLYMER POROUS CARBON ELECTRODEPOSITION Russian patent published in 2018 - IPC C25D17/00 

FIELD: technological processes.

SUBSTANCE: invention relates to devices enabling the process of electropolymerization of a heterocyclic monomer from an electrolyte solution, so that the maximum possible number of products of the polymerization reaction is formed as an even layer on the surface of the carbon carrier in order to subsequently change the electrophysical parameters of the carrier surface. Plant for porous carbon electrodeposition of conductive polymers includes a working chamber for placing an electrolyte solution with a monomer equipped with an expansion tank for discharging the electrolyte solution as it moves. Piston is located in the chamber from the bottom of the working chamber with the possibility of reciprocating movement at a controlled speed with the aim of moving the electrolyte solution in the chamber volume. Porous working electrode-anode in the form of a carbon carrier contacts the current lead and is intended to be applied to its surface by a conductive polymer and is arranged to be located in the chamber volume parallel to the working surface of the piston. Counter-electrode-cathode is necessary for passing the current to oxidize the monomer that is part of the electrolyte. Apparatus is also provided with a reference electrode for setting a certain value of the oxidation potential of the monomer on the porous working electrode.

EFFECT: electrochemical deposition of a layer of an electrically conductive polymeric composition on the surface of a carbon carrier having an equal thickness at various points on the surface and necessary for changing the electrophysical parameters of the surface of the carrier, giving it catalytic properties, changing its hydrophilicity, and a number of other applications.
