Abstract

This study investigates the impact of ultrasonication time on the electrical properties of Polyvinyl Alcohol, Zinc Oxyde, MXene, and Cellulose Nanocrystral (CNC) composites for use in electronic devices. The goal was enhance the electrochemical performance of biodegradable materials for sustainanble electronics. Composites were prepared by incorporating MXene and CNC into PVA ZnO matrix, with varying ultrasonication durations. Electrical properties, including current density and specific capacitance, were evaluated using cyclic voltammetry, while structural analysis was performed via Xray diffraction and scanning electron microscopy. The results showed a significant increase in both current density and specific capacitance as ultrasonication time increased, with value reaching 0.2727 A/cm for current density and 0.646 F/g for specific capacitance after 60 minutes of ultrasonication. These improvements were attributed to better nanoparticle dispersion and enhanced charge transport pathways. The findings demonstrate that ultrasonication is an effective method for optimizing the performance of biodegradable composites in energy storage application.
