Abstract In this study, polyvinylidene difluoride (PVDF) is doped with different volume levels (10, 20, 30 vol %) of lead zirconate titanate (PZT), and neat PVDF (undoped) electrospun nanofibres are prepared by aligning them through the electrospinning process with a rotating drum collector. All of the produced nanofibres are characterized by X-ray powder diffraction (XRD), Scanning Electron Microscopy (SEM), and Fourier Transform Infrared spectroscopy (FTIR). The piezoelectric nanogenerator (PEN) devices are fabricated by placing the PVDF/PZT electrospun nanofibres as the dielectric material between two conductive plates. The vibrational energy harvesting analyses of the PEN are defined by taking measurements under various resistive loads. At 15 Hz excitation frequency, the maximum output power of PEN with PVDF+10 vol %PZT reaches 6.35 μW by increasing the power to 85% under a resistive load of 1MΩ, while the PEN with β-PVDF has the electrical power of 3.44 μW at the same load. The PEN based energy generation is a promising source of clean energy generation from mechanical vibrations for powering portable microelectronic applications without an external power supply.

基于 PVDF/PZT 的柔性压电纳米发电机 (PEN) 的制备和振动能量收集表征

摘要 在本研究中，聚偏二氟乙烯 (PVDF) 掺杂了不同体积水平（10、20、30 vol%）的锆钛酸铅（PZT），并通过静电纺丝过程将它们对齐制备了纯 PVDF（未掺杂）电纺纳米纤维。带转鼓收集器。所有生产的纳米纤维都通过 X 射线粉末衍射 (XRD)、扫描电子显微镜 (SEM) 和傅里叶变换红外光谱 (FTIR) 进行表征。压电纳米发电机 (PEN) 装置是通过将 PVDF/PZT 电纺纳米纤维作为介电材料放置在两个导电板之间来制造的。PEN 的振动能量收集分析是通过在各种电阻负载下进行测量来定义的。在15Hz激励频率下，PVDF+10vol%PZT的PEN的最大输出功率达到6。在 1MΩ 的阻性负载下将功率增加到 85%，功率为 35 μW，而带有 β-PVDF 的 PEN 在相同负载下的电功率为 3.44 μW。基于 PEN 的能源发电是一种很有前途的清洁能源，它利用机械振动为便携式微电子应用供电，无需外部电源。
