Abstract

The electrical properties of thin films made of polyethylene oxide (PEO) dispersed with dopants fixed amount of iodine (0.1 wt. %) were studied using the AC impedance technique. The films were prepared by electrically casting method. In this present work, the variation of AC electrical conductivity with temperatures ranging from 30 oC to 55 oC at a frequency of 200 kHz for (PEO) film doped with 0.1wt. % iodine and undoped (PEO) film were studied. Physical quantities and parameters such as AC conductivity, impedance, dielectric constant, and dielectric loss, were determined. The observed values of the impedance (Z), dielectric constant ('), dielectric loss ("), and AC-conductivity (σAC) showed temperature dependence. It was found that the dielectric constant and the dielectric loss of the prepared thin films increased with doped (0.1wt. %) iodine complexes and also increased with the increase of temperature according to the polarization processes.

掺入 0.1 重量百分比碘的聚氧化乙烯的电气性能随温度的变化

采用交流阻抗技术研究了聚氧化乙烯（PEO）分散掺杂固定量碘（0.1 wt.%）薄膜的电学特性。薄膜是通过电浇铸法制备的。在本研究中，研究了在 200 kHz 频率下，掺杂 0.1 wt. % 碘的（PEO）薄膜和未掺杂的（PEO）薄膜的交流导电率随温度（30 oC 至 55 oC）的变化情况。测定了交流电导率、阻抗、介电常数和介电损耗等物理量和参数。阻抗 (Z)、介电常数 (')、介质损耗 (") 和交流电导率 (σAC) 的观测值均与温度有关。研究发现，所制备薄膜的介电常数和介电损耗随着掺杂（0.1wt. %）碘络合物的增加而增加，并且根据极化过程，也随着温度的升高而增加。
