摘要

This article details the synthesis and characterization of lead-free BCZT (B0.85C0.15Z0.9T0.1) nanopowder, which was produced using a solid-state reaction technique and fabrication of Polyvinylidene fluoride (PVDF) using solution casting. The study aimed to improve the piezoelectric properties and electrical performance of PVDF by adding different weight percentages of BCZT. The samples are characterized by using X-ray diffraction (XRD) and Fourier-Transform Infrared Spectroscopy (FTIR) by varying the weight percentages of PVDF-BCZT to analyze their influence on piezoelectric performance. The BCZT powder was mixed into a PVDF matrix (0%, 5%, 10%, 15%, and 20%). Based on the result, Impedance analysis showed that the relative permittivity increased with BCZT loading, reaching its maximum value for the 20wt.% PVDF/BCZT composite. Further result shows that 10wt.% of PVDF/BCZT sample exhibited a higher electrical voltage, increasing by 44% compared to the 5wt.% sample. Furthermore, the performance of the composite was evaluated by measuring the voltage generated under vibration testing from 1 to 10 Hz. The 10wt.% of PVDF/BCZT composite yielded a maximum output voltage of 0.3421 V. Finally, these outcomes demonstrate that the PVDF/BCZT wt.% enhances the piezoelectric performance, whereas encouraging environmentally friendly welfare and flexibility of devices.
