  • Patent number: 5151224
    Abstract: The present invention relates to a process of manufacture of an essentially smooth texture-free conductive polymer comprising poly(dithiophene) which is subsequently doped with a dopant comprising an organometallic compound, preferably an optionally substituted metal phthalocyanine. Specifically, the process relates to a process to produce a smooth, texture-free conductive polymer comprising poly(dithiophene) and an organometallic compound which process comprises:A. contacting a solution itself comprising:(a) dithiophene is present in between about 0.01 and 0.001 M concentration;(b) a water-soluble salt of an optionally substituted organometallic wherein the metal is selected from iron, copper, cobalt or nickel, at a concentration of between about 0.01 and 10 mM;(c) in a solution of acetonitrile/water in a ratio of between about 30:70 and 10:90 percent by volume with a cycling potential of between about 0.1 volts and 10 volts at between about 0.degree. and 95.degree. C. for between about (0.
