  • Patent number: 5720903
    Abstract: A dispersible, intrinsically conductive polymer having an electrical conductivity (measured in a 4-point measuring cell on a powder pellet) of 2.5.times.10.sup.1 to 2.5.times.10.sup.5 S/cm is obtained when a dispersible intrinsically conductive polymer in powder form having a starting conductivity of 1 to 5 S/cm is rubbed and/or dispersed in the presence of a non-polymeric polar substance applying sufficient shear forces until the desired increased electrical conductivity is reached.
    Type: Grant
    Filed: November 17, 1995
    Date of Patent: February 24, 1998
    Assignee: Zipperling Kessler & Co. (GmbH & Co)
    Inventors: Bernhard Wessling, Holger Merkle, Jr., Susanne Blattner
  • Patent number: 5498761
    Abstract: The present invention relates to a process which comprises the steps of producing moldings from intrinsically conductive polymers on a substrate, the moldings being conductive layer components having a specific conductivity of >10.sup.-2 S/cm, by depositing a predetermined amount of a metastable dispersion of the intrinsically conductive polymers to form the conductive component.
    Type: Grant

    Inventors: Bernhard Wessling, Holger Merkle
  • Patent number: 4806212
    Abstract: An electrode based on conductive material and macromolecular materials as the binder, which is stable under electrolysis conditions and is particularly suitable for drying masonry, comprising(A) a thermoplastic polar polymer, polycondensate or polyadduct or a mixture thereof, which is wettable by an electrolysis medium and is stable with respect to an electrochemical process taking place on the electrode, and(B) a mixture in a weight ratio of 1:4 to 4:1 of(a) conductive carbon black with a BET-surface of more than 600 m.sup.2 /g and/or an intrinsically conductive polymer and(b) carbon black with a BET-surface of less than 600 m.sup.2 /g and/or graphite and/or transition metal oxides and/or an intrinsically conductive polymer.
