EFFECTS OF 0.1 WT.% IODINE ADDITIVE ON DIELECTRIC BEHAVIOR AND AC ELECTRICAL CONDUCTIVITY OF POLYETHYLENE OXIDE FILMS

Abstract

This paper aimed to investigate the electrical characteristics of thin films formed of polyethylene oxide (PEO) distributed with dopants containing a fixed quantity of iodine (0.1 wt.%). The alternating current (AC) electrical properties were studied using the AC impedance technique in the frequency range 3kHz–5MHz and temperature range 30–55oC. The electrically prepared films were made using the casting procedure. This paper compared the variation of AC electrical conductivity with frequency for PEO doped with an iodine-doped polyethylene oxide film and determined some physical quantities and parameters such as AC conductivity, impedance, dielectric constant, and phase angle. The impedance (Z), dielectric constant (e'), dielectric loss (e"), and AC conductivity data observed revealed frequency and temperature. According to polarization processes, the dielectric constant and dielectric loss of the produced thin films increase with doped iodine complexes and decrease with frequency. Iodine, temperature, and frequency all improve AC conductivity.
