Organic-inorganic lead halide perovskite materials are emerging as promising materials with excellent performance in energy harvesting and sensors. We prepare the piezoelectric materials based on a composites of piezoelectric formamidinium lead halide perovskite(FAPbBr3) and poly(vinylidene fluoride) (PVDF) using in-situ fabrication process. The composite materials were coated in ITO deposited glass and polymer substrates. Also, the composite films were in detail characterized by spectroscopy, field-emission transmission electron microscopy (FE-TEM), x-ray diffraction(XRD) measurement system. The piezoelectric NGs was fabricated to evaluate the piezoelectric output voltage and current density. The FApbBr3-PVDF composite films obtained under the optimized conditions showed outstanding piezo performance. These composite films would be expected to be suitable for applications in electronic devices, and smart sensors. |
