Enhancing Energy Harvesting Efficiency with BaTiO3/PDMS/MWCNT Nanocomposites

EasyChair Preprint no. 13793

Abstract

Energy harvesting technologies are crucial for sustainable energy solutions, and enhancing their efficiency is a key research focus. This study explores the use of BaTiO3/PDMS/MWCNT nanocomposites to improve the energy harvesting efficiency of piezoelectric devices. Background: Barium Titanate (BaTiO3) is known for its excellent piezoelectric properties, while Polydimethylsiloxane (PDMS) offers flexibility and mechanical robustness. Multi-Walled Carbon Nanotubes (MWCNT) are incorporated to enhance electrical conductivity and mechanical strength. Methods: The nanocomposites were synthesized using a solution casting method, followed by characterization through scanning electron microscopy (SEM), X-ray diffraction (XRD), and piezoelectric response measurements. Results: The BaTiO3/PDMS/MWCNT nanocomposites exhibited a significant increase in piezoelectric output compared to pure BaTiO3 and BaTiO3/PDMS composites. The optimal concentration of MWCNT was found to be 1% by weight, resulting in a 30% increase in energy harvesting efficiency. Conclusion: The incorporation of MWCNT into BaTiO3/PDMS nanocomposites enhances their piezoelectric properties and energy harvesting efficiency, making them promising candidates for advanced energy harvesting applications.
