Abstract

L'invention concerne la fabrication des électrodes. Pour augmenter la résistance de contact entre une électrode métallique et un revêtement de polymère conducteur, on met en contact cette électrode et la composition de polymère pendant que la composition est à une température Tp supérieure au point de fusion Tm de la composition et que le métal est à une température Te supérieure à Tm , pendant un temps suffisant pour diminuer la résistance de contact mais non suffisant pour diminuer notablement la résistivité de la composition.The invention relates to the manufacture of electrodes. To increase the contact resistance between a metal electrode and a coating of conductive polymer, this electrode is brought into contact with the polymer composition while the composition is at a temperature Tp above the melting point Tm of the composition and the metal is at a temperature Te greater than Tm, for a time sufficient to reduce the contact resistance but not sufficient to significantly reduce the resistivity of the composition.
