摘要

In this investigation, novel PVDF-metal oxide (MO) nanocomposite-based systems were meticulously developed and thoroughly characterised. Employing an eco-friendly green synthesis process, a polymer-metal oxide nanocomposite system was successfully constructed using two distinct nanoparticles. The integration of nanocomposite systems was accomplished using the versatile sol–gel technology, and an innovative spin coating method was utilised to create the nanocomposite thin films without requiring an electrical field or a post-processing poling step. The characterisation encompassing morphology, structural, electrical, and piezoelectric performance was conducted. Notably, all PVDF/MO nanocomposite thin films surpassed the individual PVDF thin film in piezoelectric performance, demonstrating their exceptional potential. Among them, the PVDF nanocomposite doped with ZnO and TiO2 exhibited the most promising and superior piezoelectric performance. The outstanding piezoelectric capabilities displayed by The PVDF/MO nanocomposite systems offer remarkable potential for their utilization as an innovative energy source in nanogenerators, making them an enthralling option for future applications.
