Impedance Spectroscopic Studies on Natural Rubber-TiO2 Nanocomposite

In this study, we demonstrate dielectric properties of Natural rubber-TiO2 (NR-TiO2) nanocomposite. We fabricated a device by sandwiching NR-TiO2 nanocomposite between two different work function electrodes aluminium and Indium Tin Oxide (ITO). Capacitance versus voltage analysis showed a nonlinear behavior as that of an organic Schottky diode. Variation of real and imaginary part of dielectric constant with different frequencies was studied by using Electrochemical Impedance spectroscopy (EIS). Validity of the impedance data was evaluated by using theoretical Kramers-Kronig relations and the obtained results showed an acceptable match with high degree of consistency.
