Abstract

This study investigates the dielectric properties, including dielectric constant (ɛ′), dielectric loss (ɛ″), tangent delta (tan δ), and AC conductivity (σ<subscript>ac</subscript>), of PVA/Y<subscript>2</subscript>O<subscript>3</subscript> polymer nanocomposites (PNCs). The dielectric behavior of the PNCs was examined as a function of frequency and temperature. The results revealed that the addition of Y<subscript>2</subscript>O<subscript>3</subscript> nanoparticles to the PVA matrix influenced the dielectric properties of the composites. In contrast to pure PVA, the PVA/Y<subscript>2</subscript>O<subscript>3</subscript> PNCs with a 15 wt% Y<subscript>2</subscript>O<subscript>3</subscript> loading exhibited high values of ɛ′, ɛ″, tan δ and σ<subscript>ac</subscript> are 647.49, 1607.48, 9.70 and 1.024 × 10<superscript>−5</superscript>, respectively, at low frequency and at particular temperature. Furthermore, the electrical properties of PVA/Y<subscript>2</subscript>O<subscript>3</subscript> PNCs were also investigated using the Cole-Cole plots. These plots provide valuable insights into the complex impedance behavior and allow for comprehensive understanding of the electrical response of the nanocomposites. [ABSTRACT FROM AUTHOR]
