Abstract
Abstract In a composite material consisting of a porous material and electrically conductive polymers, the surface of the pores of the porous material is first coated with a layer of an electrically conductive polymer obtained by treating the monomers with an oxidizing agent, and a layer of an electrically conductive polymer obtained by anodic oxidation of the monomers is applied on top of this.
