Abstract

Thermo-electrets of poly (vinyl chloride-co-vinyl acetate-co-2 hydroxy propyl acrylate) PVVH and its nanocomposite PVVH/ZnO were prepared using the thermal poling method. Thermally stimulated depolarization current TSDC technique used to study the alpha relaxation of the samples. The global spectra of the nanocomposites revealed that ZnO nanoparticles are completely compatible with the polymer matrix. The activation energy was calculated and found to be in the range of 0.69-1.25 eV. TS technique was used to resolve the complex TSDC behavior and thermodynamic parameters were obtained from Eyring relationship which verified the linear relation between the activation enthalpy ΔH and the activation entropy ΔS. The compensation phenomena had been studied and the degree of disorder DOD of all samples has been calculated and results values in the range 15 to 35.24 Cal degree^-1.
