| dc.description.abstract | The electrochemical behaviour of the three compounds (pyrrole, thiophene and aniline) was studied by various electroanalytical teclmiques (dc and ac-cyclic voltammetry, linear sweep voltammetry, chronoamperometry, chronocoulometry). The influence of ~weep rate on the voItammetric behaviour of pyrrole and 3-methyIthiophene in nitrobenzene is discussed. The - effect of anoding switching potential on the voItammetric behavior of pyrrole is also discussed. An attempt was made to prepare polythiophene film in nitrobenzene using various-supporting electrolytes (lithium perchlorate, tetrabutylammonium perchlorate, tetraethylammonium tetrafluoroborate) on different electrodes. But no polymer was formed. The ac-cyclic and impedance measurement teclmiques were used to characterize aniline oxidation in sulfuric acid. The variation of the peak current with frequency is discussed. Also the cyclic voltammograms of polyaniline film coated Pt electrode obtained in sulfuric acid were studied. The impedance spectroscopy of polyaniline film in the direction of the potential scan from positive to negative and from negative to positive has also been studied | en_US |
