Abstract

Electrochemical polymerization of pyrrole (Py) in an excess of acrylamide (AAm) was accomplished by using an acetonitrile-tetraethyl ammonium perchlorate (TEAPC) solution containing both monomers. Characterization of soluble and insoluble products was carried out via FT-IR spectrum, cyclic voltammogram (CV), W-visible spectrum, scanning electron microscope (SEM), differential scanning calorimetry (DSC) and elemental analysis. The role of monomer concentrations on the formation of resulting polymer was investigated. Since the polymerization rate of Py is faster than that of AAm, the appropriate ratio of concentrations of monomers have chosen to have chance to interact AAm with Py oligomers which was formed immediately on the electrode surface. Inclusion of AAm to polymer and the mole ratio of resulting product was reported. (C) 1999 Elsevier Science S.A. All rights reserved.
