摘要

Polymer-based nanocomposites are considered promising candidates for flexible modern electronic devices. ZnO-PVA polymer nanocomposites have gained recent research interest due to excellent optical and dielectric properties. Transition metals (Cr, Mn, Fe, Ni, Cu) oxide nanoparticles incorporated ZnO-PVA composite matrix are investigated in this work for a comprehensive study of its structure, morphology, optical and dielectric parameters. Crystallographic information revealed the presence of crystalline zinc oxide and transition metals oxides reflections in specific orientations in the PVA matrix. The inter-particle distance and interfacial interaction of transition metal oxide nanoparticles in host polymer are observed as important factors for improved dipole polarization. The nanoparticles of metal oxides in matrix induce the enhanced negative charge carriers and exhibit robust interactions with positive carriers of the polymer surface. A sharp and substantial increment in real dielectric permittivity from 74 for ZnO-PVA to maximum 350 for ZnO-PVA-Fe(2)O(3)composition was observed by the addition of transition metal oxides in the PVA matrix with same loss factor value of 0.1.
