  • Publication number: 20050127331
    Abstract: A molecular complex which includes a template having a plurality of ionic functional groups and a conducting polymer. The conducting polymer may be polypyrrole, polythiophene or poly(phenylene sulfide) and substituted versions thereof. The conducting polymer has charges on it which bind to the organic functional group. The complex has a polypyrrole ration of between about 0.5 to 4.5.

  • Publication number: 20050113559
    Abstract: This invention is directed to the synthesis of double-stranded conducting polymers, formulation for surface treatment reagents, and the use of water-borne double-stranded conducting polymers. The double-stranded conducting polymer provides a unique flexibility in designing molecules for surface treatment. The compositions can be used to treat metal surfaces to provide a stable interface for adhesive binding or the coating of paint or plastics on top of the chemically modified surface. The composition is useful as a replacement of chromate-based surface treatment process.
