The Electrochemical Behavior in Aqueous Media of Conducting Polymers: I: The Methanol Soluble Fraction Obtained on the Cu(II) Catalyzed Polymerization of 2,5-Dibromo-3-Methylthiphene
Abstract:Abstract

The methanol soluble amorphous fraction obtained on the CuCl2 induced polymerization of 2,5-dibromo-3-methylthiophene exhibits redox waves on cyclic voltammetric potential polarization for a copper redox couple (for the metal ion incorporated in the polymer matrix) and a redox couple associated with the polymer matrix itself. Furthermore, when used as an electrode for the ferri/ferrocyanide couple in the electrolyte phase it acts as a well behaved electrode surface. Electrodes made from this material show a remarkable stability in aqueous media.
Keywords:Conducting polymers  Poly(thionylenes)  Polymer Electrodes  Aqueous Electrolyte  Cyclic Voltammetry and  Cu(II)/Cu(O) Redox Couple
