Özet
The electrochemical polymerization of conducting polymers is a simple and most convenient method for preparation of a film on the metal surface. The polypyrrole/chitosan composite film has been electrochemically synthesized on platinum electrode by using cyclic voltammetry (CV) technique. The synthesis solution was prepared by dissolving of pyrrole and chitosan in aqueous oxalic acid solution. The characterization of this film was done using Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and thermal analysis (TG-DTA) techniques. The synthesized composite film was different in aspect of morphology when compared to chitosan and polypyrrole. The TG-DTA results revealed that the composite film had better thermal stability with respect to chitosan. The electrochemical measurement has shown that the composite film is very stable and electroactive. (C) 2009 Elsevier Ltd. All rights reserved.
