Abstract

Polymer composite (PC) films comprising polyvinyl alcohol (PVA) and poly(3,4-ethylene dioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) with manganese dioxide (MnO2) as filler were prepared by simple solution casting method. The structural confirmation of PCs was investigated by Fourier transform Infrared Spectroscopy (FTIR) and X-ray diffraction (XRD) techniques. The morphological and thermal properties were analyzed using scanning electron microscope (SEM) and thermogravimetric analysis (TGA). Under the frequency range, 50 Hz to 20 MHz, and temperature from 40 to 150 °C, the dielectric properties and Q-factor values for the as-synthesized PC films were investigated by an impedance analyzer. PVA/PEDOT:PSS/MnO2 having wt% 50:35:15 revealed high dielectric constant (ε) at 1949 and low dielectric loss(tanδ) at 8.13. The obtained results suggest that the titled PC films are effective materials for energy storage applications.
