The Composition of “Cu(II)-Poly(3-Methylthiophene) Conducting Polymer” Electrodes

Abstract The electrode material formed on the chemical polymerization of 3-methylthiophene using Cu(II) salts as catalysts had been previously reported to be a poly(3-methylthiophene) incorporating coordinately bound Cu(II). Further examination of the nature and composition of this material by FTIR, EPS, elemental analysis and cyclic voltammetry reported here shows that this material is actually a composity of Cu(I) and Cu(II) cyanide in a matrix containing poly(3-methylthiophene).
