Optimizing BaTiO3 Content in Flexible PVDF Films for Enhanced Piezoelectric Nanogenerator Performance

Year: 2025

Type: article

Abstract: This study addresses the underutilized potential of harvesting mechanical energy from routine human activities, while also addressing environmental and flexibility concerns associated with conventional lead-based piezoelectric materials. With the increasing demand for sustainable and eco-friendly energy solutions, lead-free piezoelectric technologies have emerged as a promising alternative, particularly in the development of flexible nanogenerators. In this study, the flexible PVDF/BaTiO₃ composite films fabricated via drop casting with varying BaTiO₃ filler loadings (1 wt%, 3 wt%, and 5 wt%) were analyzed for their influence on piezoelectric performance. Characterization techniques included contact angle analysis, FESEM, XRD, FTIR, and piezoelectric output. Results showed that 1 wt% BaTiO₃ yielded the highest output voltage (8.24 V), attributed to optimal β-phase formation. However, loadings beyond 3 wt% led to void formation and particle agglomeration, reducing β-phase crystallinity and overall performance. These findings demonstrate that controlled BaTiO₃ loading enhances piezoelectric performance while promoting environmental safety and device flexibility.
