Abstract
Although polyaniline has a high electroactivity in environments below pH 5, it loses its electroactivity in neutral and basic environments. In addition, polyaniline film does not give physically stable film when it becomes thick. For these reasons, polyaniline has been synthesized in the presence of other monomers or inorganic/organic species, leading to the obtaining of composite polymers with some new electrochemical and physical properties. In this study, novel composite polymer films of polyaniline were synthesized electrochemically in the presence of different concentrations of Na2MoO4.2H2O and Na2WO4.2H2O, and these composite polymer films were examined in monomer-free solutions for electrochemical investigation. As a result, the cathodic charge of polyaniline increased from 0.25 mC to 1.50 mC in the presence of 0.05 M Na2MoO4.2H2O. Also, the polyaniline/WO3 composite achieved a charge transfer of 0.42 mC in the presence of 0.25 M NiSO4.2H2O, 0.05 M NiCl2.6H2O, Na2WO4, Na2MoO4.2H2O, 0.4 M Na3C6H5O7.2H2O and 0.05 Na2WO4.2H2O as a metal source. These prove the better charge transfer during the redox reaction of the polyaniline composite film.
