Electrical Properties of Polymer Nanocomposites

Abstract

The utilization of green system engineering approaches to achieve biodegradable, eco-friendly, and high-value materials from enduring cellulosic biomass can share the viability of forthcoming biorefineries. We studied the possibility of sugarcane bagasse as cellulosic biomass to recover nanocellulose from chemical treatment and mechanical milling process. Polymer-based nanocomposites dielectric exhibit a vast possibility in high voltage wires for their apparent enhancements to the electrical characteristics. In the current investigation, the nanocomposites consist of epoxy polymer, sugarcane nanocellulose, and aluminum silicon carbide (Al-SiC) nanoparticles are investigated using an ultrasonication-assisted wet layup technique. The appearance of Al-SiC nanoparticles enhances the dielectric characteristics such as the inhibition of space charge and direct current breakdown strength. The thermally stimulated current and electrical conductivity properties signify the deep captures in the laminate increment evident. The dielectric permittivity of chemically treated sugarcane nanocellulose fiber and Al-SiC-reinforced epoxy hybrid nanocomposites was five times higher than the untreated ones. Our method offers a hasty technique to produce a lower dielectric loss factor and a higher dielectric constant of sugarcane nanocellulose and Al-SiC-reinforced polymer nanocomposites using the manufacturing of Al-SiC-encapsulated epoxy microspheres. © 2022 Elsevier Ltd.
