Enhanced Dielectric Characteristics of Cr2O3 Nanoparticles Doped PVA/PEG for Electrical Applications

Abstract

This study examines the dielectric properties of polyvinyl alcohol (PVA)/polyethylene glycol (PEG) doped with chromium oxide (Cr2O3) nanoparticles, with the aim of leveraging these properties in electronic and electric nanodevices. The effect of Cr2O3 nanoparticle concentration on the dielectric constant, dielectric loss, and AC electrical conductivity of the composites was systematically investigated. The results demonstrate that both the dielectric constant and dielectric loss decrease with increasing frequency, but increase with the concentration of Cr2O3 nanoparticles. Conversely, AC electrical conductivity was found to increase with both frequency and Cr2O3 nanoparticle concentration. The enhanced dielectric properties of the PVA/PEG/Cr2O3 nanocomposites make them suitable for various applications in the field of electronics and energy storage. The study provides new insights into the design of materials for electrical and electronics applications.
