  • Patent number: 7332223
    Abstract: This invention presents polymers and copolymers comprising repeating units of thieno[3,4-b]thiophene. Water-borne dispersions of such polymers and copolymers can be cast by conventional methods to provide uniform, thin films which possess utility in numerous electroactive applications including electrochromic displays, optically transparent electrodes and antistatic coatings. The compositions of this invention can be doped with conventional p-dopants or n-dopants. The invention also presents an aqueous process for preparing such compositions of matter.

  • Patent number: 7321012
    Abstract: A method of manufacturing an intrinsically conductive polymer crosslinking at least a portion of an intrinsically conductive polymer precursor in the solid state, the swollen state, or combinations comprising at least one of the foregoing states, wherein the swollen state is characterized as being one wherein the intrinsically conductive polymer precursor increases in volume upon exposure to a solvent without completely dissolving in the solvent. In another embodiment, a method of manufacturing a pattern comprises casting a film of an intrinsically conductive polymer precursor on a substrate; and crosslinking at least a portion of the film by oxidation, wherein the crosslinking occurs in the solid state, the swollen state or combinations comprising at least one of the foregoing states.
