ELECTROPOLYMERIZATION OF ANILINE AND PYRROLE IN THE PRESENCE OF COPPER(II)

Polymerization of aniline and pyrrole in the presence of copper(II) coming from different salts were studied by cyclic voltammetry. The systems used are: polymer/CuCl2/HCl, polymer/CuSO4/H2SO4 and polymer/Cu(NO3)2/HNO3 ). The polymer/metal mol ratios were 10/1 in both cases. The voltammograms were r...
