Abstract
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.
