TLDR
In this article, the authors successfully modified water soluble resin polyvinyl alcohol (PVA) by loading zirconium sulphate (ZrSO4) and demonstrated the measurement of electrical properties by using impedance analyser across frequency range (10 Hz-1 MHz) and the temperature range of (30°C to 150°C).Abstract:
We successfully modified water soluble resin polyvinyl alcohol (PVA) by loading zirconium sulphate (ZrSO4). We demonstrated the measurement of electrical properties by using impedance analyser across frequency range (10 Hz-1 MHz) and the temperature range of (30°C to 150°C). The impedance spectroscopy demonstrates decrease in bulk resistance as a function of temperature loading of zirconia 2.5 wt. %. Increase in AC (10−5 S/cm and DC conductivity (10− 2 S/m) observed due to ionic contribution of zirconia. However, the electrical properties of PVA/ZrSO4 composite useful to develop battery electrolyte applications.read more

Effect of molecular weight on dielectric properties of polyvinyl alcohol films
Girish M. Joshi,S. M. Pawde +1 more
TL;DR: In this paper, two different molecular weights of polyvinyl alcohol (PVA) films were used for impedance analysis, and the results showed higher magnitude of dielectric constant for low-molecular weight (LMW) of PVA film in comparison to higher molecular weight (HMW), which is based on Maxwell-Wagner (M-W) theory.
