摘要

The present work deals with the characterization of a thin film polymer electrolyte based on poly( N -vinyl pyrrolidone) (PVP) doped with ammonium iodide (NH~(4)I) and carbon nanotubes (CNT) as dispersoid to develop nanocomposite polymer electrolyte films using solution cast method. Carbon nanotubes were incorporated in PVP:NH~(4)I matrix in different concentration. Electrochemical impedance spectroscopy technique was used for characterizing the polymer electrolyte system. 0.4 wt% MCNT containing system shows maximum conductivity (8.23 × 10_(−2) S/cm). The temperature dependent conductivity studies reveal the Arrhenius behavior. Differential scanning calorimetry analysis shows the decrease in the glass transition temperature (Tg) from 345 (60:40 PVP:NH~(4)I) to 339 K (60:40 + 0.4 wt% PVP:NH~(4)I + CNT). Dielectric phenomenon, concentration of charge carrier density (N) and dissociation factor also supports the conductivity data while ionic transference number (t~(ion)) studies confirms the ionic conductive nature of the electrolyte system.
