Patent ID: 6878355

Claim:
A chemical device for depositing conductive polymer on complex porous cross-linked foam, felt or woven material structures to impart electrical conductivity to said structures, characterized in that it includes one or more reactors in which the various conductive activation treatment steps are effected within said structures, throughout the thickness thereof, on the surface of each of their fibres or meshes, without clogging their pores, to impart to them a continuous electrical conductivity over the whole of their developed surface, and in that it enables treatment of structures of varying thicknesses and shapes, in particular in the form of blocks or rolls (cylinders formed by a rolled strip), throughout their volumes, and without unrolling them in the case of rolls, the various treatment solutions being passed through said blocks or rolls, the device including at least one reactor equipped with a hollow, perforated and rotatable core onto which the porous structure block or roll to be treated is fitted, said core being used to inject the treatment solutions used into the block or roll and/or to aspirate it therefrom and/or to rotate the block or roll on itself in order to homogenise the diffusion of the fluids within it and/or to expel said fluids centrifugally.
