AC CONDUCTIVITY AND DIELECTRIC BEHAVIOUR OF ETHYL CELLULOSE/POLYVINYL ALCOHOL POLYBLEND THIN FILMS

The study investigates the AC conductivity and dielectric behavior of ethyl cellulose (EC) and polyvinyl alcohol (PVA) polyblend thin films, aiming to explore their potential applications in electronic and dielectric devices. The objective of this study is to analyze the electrical conductivity and dielectric constant of Ethyl Cellulose (EC) blended with polyvinyl alcohol (PVA) at different temperatures (303K,313K, 323K, 333K, and 343K) and across a frequency range of 1 kHz to 1 MHzs Measurements were conducted using a 4284 LCR meter. The results indicate that the AC conductivity of the thin film changes with temperature for all frequency values and also increases with frequency at a constant temperature. Additionally, the dielectric constant exhibits variations with increasing temperature in the polymer blends.
