Method and apparatus for continuous manufacture of a laminate comprising a layer of a conductive polymer and at least one electrode. A tape electrode and a heat-softened conductive polymer are fed simultaneously through an elongate aperture of substantially closed cross-section formed by a plurality of rollers, whereby there is produced a laminate in which the conductive polymer layer has a controlled cross-section. Preferably the electrode has a plurality of openings therein and is fed through the aperture so that there is at least one point on the electrode, as it passes through the aperture, which coincides with an angle which is formed by two of said rollers and which is at most 90°. Particularly good results are obtained when the roller which contacts the electrode has a plurality of indentations therein, so that conductive polymer not only penetrates into the openings in the electrode but also passes through those openings which overlie the indentations in the roller. Novel laminates are produced in this way.

A method of making a laminate comprising a layer of a conductive polymer composition and an electrode in contact with said layer, which method comprises (1) forwarding an electrode in the form of a tape having a plurality of openings therein through an aperture of substantially closed cross-section

A method of making a laminate comprising a layer of a conductive polymer composition and an electrode in contact with said layer, which method comprises (1) forwarding an electrode in the form of a tape having a plurality of openings therein through an aperture of substantially closed cross-section which is formed by a plurality of rollers which rotate so as to forward material in contact with the rollers through said aperture, said electrode being in contact with at least one of said rollers and thereby being forwarded through said aperture, and said roller contacted by said electrode having a plurality of indentations in the surface thereof, whereby first areas of the electrode are in contact with said roller and second areas of said electrode overlie said indentations; (2) simultaneously feeding a heat-softened conductive polymer composition into said aperture at a rate sufficient to fill said aperture, whereby said composition is forwarded through said aperture in contact with said electrode and penetrates into but not through openings in said first areas of the electrode and penetrates into and through openings in said second areas of the electrode.
