Sustainable Production of Polymer Matrix Nanocomposites for Energy Storage

Abstract

This research investigates the manufacture of polymer matrix nanocomposites specifically designed for energy storage applications with a focus on sustainability. Four kinds of polymers (PVA, PLA, PET, PMMA) were created with different percentages of nanofillers (ranging from 1.0% to 2.0%) and polymer concentrations (ranging from 2.5% to 4.0%). The mechanical testing results showed Young's modulus values ranging from 11.8 GPa to 15.2 GPa, and corresponding tensile strengths ranging from 42.9 MPa to 50.2 MPa. The electrical conductivity tests revealed a conductivity range spanning from 1.8 x 10^-3 S/cm to 2.5 x 10^-3 S/cm. The assessment of energy storage capability revealed capacitance values ranging from 115 F/g to 135 F/g, with charge-discharge efficiencies varying between 91.8% and 94.3%. The findings highlight the capability of polymer matrix nanocomposites to achieve customized properties that are favorable for energy storage. This emphasizes the significance of logical design, manufacturing methods, and sustainability factors in advancing these materials for practical use in the renewable energy industry.
