| Popis: | In this research article, as-synthesized polythiophene (PTh) were analyzed through FTIR, XRD, FESEM and TG/DTA techniques. The polymerization of PTh were confirmed through FTIR and XRD analysis. The temperature dependence of DC electrical conductivity of the samples has been obtained over a temperature range from 303 to 393 K followed Arrhenius relation. The DC conductivity of the samples was found to be in the range of 10−6–10−4 S cm−1. The activation energies of the samples were ranges between 0.23 and 0.14 eV. The variation of AC electrical conductivity with frequency obeys Jonscher power law. Moreover, dielectric studies were made using AC impedance analyzer in the frequency and temperature ranges 20 Hz–1 MHz and 303–393 K, respectively. The maximum value of DC conductivity was found to be 2.14 × 10−4 S cm−1 at 348 K for PTh with stoichiometric ratio (70:30) wt% of thiophene and FeCl3, which increases with temperature. |
