Abstract
A complex porous structure of a reticulated foam, felt or fabric types, wherein their metallisation over their entire developed surface, by electrolysis of lead or lead alloys, is made possible by a specific preliminary conductive activation treatment obtained by using two consecutive phases of coating the developed surface of the structures, comprising a first deposition of a conductive polymer, which provides the structures with the required conductivity, and a second thin deposition of conductive lacquer or varnish which ensures the surface protection of the conductive polymer against the deactivating effect of the conductive nature of the latter, due to the cathodic polarisation of the said structures in the electrolytic lead-coating bath.
