Studies on Electrical, Dielectric and Seebeck Measurement of Polyaniline-Cadmium Oxide Nanocomposite

The basic aim of this research work is to synthesize polyaniline and polyaniline-cadmium oxide nanocomposites with different concentrations by using in-situ chemical polymerization methods. The effect of cadmium oxide content on structural and morphological features of the polyaniline matrix are discussed in detail. As the concentration of cadmium oxide in polyaniline matrix augments, then crystallinity of the nanocomposites increases. Two probe methods for temperature dependent dielectric measurements revealed that electrical conductivity of nanocomposites increases with increase in temperature and cadmium oxide content. The response of permittivity to temperature is increased with increasing the cadmium oxide concentration in the nanocomposite and frequency. Four probe methods of Seebeck coefficients exhibit linear increase for nanocomposites with temperature as well as cadmium oxide content.
