Effects of Temperature, Pressure, and Frequency on Electrical Conductivity and Dielectric Behavior of PVA Nanopolymers

Abstract

In this study, electrical conductivity and dielectric properties were investigated regarding the pure polyvinyl alcohol (PVA) nanopolymer among a variety of temperatures and pressures and at various operating frequencies. At various temperatures, the electrical conductivity, loss factor, and real element of the dielectric constant were determined. The temperatures were 25, 40, 80, 120, and 160 °C with pressures of 7.5, 8, 8.5, 9, and 9.5 MPa. In addition, the selected operating frequencies were 50 Hz, 100 kHz, 400 kHz, 1 MHz, and 3 MHz. Results demonstrate that the behavior of electrical conductivity has improved under the influence of temperature, pressure and frequency. Moreover, The loss factor values vary with frequency and are linearly related to both temperature and pressure.
