Abstract

AC electrical properties were studied using the AC impedance technique. The electrical properties of thin films made of poly (ethylene oxide) (PEO) dispersed with dopants fixed amount of carbon black (0.1wt. %) were used in this study. The prepared films by casting method have been electrically. The present study has studying the change in the real part (M ') and imaginary (M ``) part of the electric modulus versus frequency of PEO thin films doped with carbon black at different temperatures, frequency in the range (200 kHz - 1000 kHz) and temperature in the range (30 0C-55 0C), and the study the real part (M ') part of the electric modulus for (PEO) with doped 0.1wt. % carbon black (CB) as compared to that case of the un doped (PEO) film. It was found that the real part (M ') of the electric modulus increases with frequency and decreases with temperatures with doped 0.1wt. % carbon black content. And it was found that the real part (M ') of the electric modulus decreases with doped 0.1wt. % carbon black content.
