▎ 摘　　要

This paper presents and compares films made using the solution casting method with a mixture of poly (vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP), graphene oxide (GO), and lead zirconate titanate (PZT). The Hummers' method synthesized GO. Scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), differential scanning calorimetry (DSC), thermal gravimetric analysis (TGA), and tensile testing were realized. The developed composite films were found to have a coherent distribution of PZT and GO in PVDF-HFP. After that, a gradual improvement, such as an increase in the quantity of beta phase, produces high piezoelectric performance. Also, the PVDF-HFP polymer's thermal stability improved. When 0.1 wt% of PZT/GO was added, the melting temperature increased from 140 to 143 & DEG;C, and the crystallization temperature from 109 to 113 & DEG;C. PVDF-HFP elastic modulus and tensile strength were also considerably reduced as PZT/GO increased. As a result, this has enabled us to develop composite films with important properties that can be used as piezoelectric materials for energy harvesting.
