Abstract

This study aimed to fabricate lead-free PVDF-BaTiO3 + ZnO and PVDF-BaTiO3/PVDF-ZnO electrospun nanofibers to enhance the piezoelectric properties of PVDF-BaTiO3 nanofibers through the incorporation of ZnO nanoparticles and PVDF-ZnO nanofibers. Field emission scanning electron microscopy (FE-SEM) was utilized to examine the morphology, size, and formation of the nanofibers, revealing well-formed structures with a reduced average diameter. Fourier-transform infrared spectroscopy (FTIR) was conducted to analyze and compare the content of β-phase in the nanofibers, indicating a higher β-phase content in both PVDF-BaTiO3 + ZnO and PVDF-BaTiO3/PVDF-ZnO electrospun nanofibers compared to PVDF-BaTiO3 electrospun nanofibers alone. The piezoelectric performance, measured as an output voltage generated by the nanofibers under applied pressure using a custom device, demonstrated improved results when ZnO nanoparticles and PVDF-ZnO nanofibers were incorporated into the structure. The findings of this investigation suggest that the addition of ZnO nanoparticles and PVDF-ZnO nanofibers into PVDF-BaTiO3 nanofibers leads to better piezoelectric composites, making them suitable for applications in energy harvesting and wearable electronic devices.

双向静电纺丝法制备ZnO纳米粒子增强PVDF-BaTiO3纳米纤维的压电性
本研究旨在制备无铅PVDF-BaTiO3 + ZnO和PVDF-BaTiO3/PVDF-ZnO静电纺纳米纤维,通过ZnO纳米粒子和PVDF-ZnO纳米纤维的掺入来增强PVDF-BaTiO3纳米纤维的压电性能。利用场发射扫描电镜(FE-SEM)研究了纳米纤维的形态、尺寸和形成,揭示了平均直径减小的良好结构。傅里叶变换红外光谱(FTIR)分析和比较了纳米纤维中β相的含量,发现PVDF-BaTiO3 + ZnO和PVDF-BaTiO3/PVDF-ZnO静电纺纳米纤维中β相的含量高于单独PVDF-BaTiO3静电纺纳米纤维。利用定制的装置测量了纳米纤维在施加压力下产生的输出电压,结果表明,将ZnO纳米颗粒和PVDF-ZnO纳米纤维掺入该结构后,压电性能得到了改善。本研究结果表明,在PVDF-BaTiO3纳米纤维中加入ZnO纳米粒子和PVDF-ZnO纳米纤维可以获得更好的压电复合材料,使其适合于能量收集和可穿戴电子设备的应用。
