The invention concerns complex porous structures varying in thickness and the method used for making them electrically conductive by conductive polymer deposit. The conductive activation is obtained by depositing a conductive polymer, set on the whole developed surface of the structure through its entire thickness, by pre-treatment steps for oxidizing the structure, depositing a monomer, polymerizing oxidaton-doping of the monomer. The structures are of the type crosslinked foam, felt or woven fabric and are mass-treated by flowing treatment solutions within blocks, still unwound rolls. Said structures, which can be metal-coated or not, are particularly designed to be used as electrodes for the electrolysis of effluent liquids, detecting and trapping organic or biological molecules, supporting electrodes for electrochemical generators, catalyst supports, filtering media, sound insulating materials, electromagnetic, nuclear, antistatic protecting structures, heat exchangers and others.
A process for the chemical deposition of a conductive polymer on porous structures of cross-linked foam, enabling said structures to be rendered electrically conductive, performed in the interior of said structures, within the entire thickness of the structures, at the surface of each fiber or mesh, without clogging the pores, rendering them continuously electrically conductive over the entire available surface area, which enables the treatment of structures presented in the form of blocks or rolls, in the latter case without unrolling, by impregnation throughout their entire volume with treatment solutions, and in that it includes the following steps:
