In this research paper, a flexible piezoelectric energy harvesting device based on Ca-doped ZnO (CaZ) nanofiller reinforced poly(vinylidene fluoride-trifluoroethylene) (PVDF-TrFE) composite film has been fabricated and evidenced with enhanced dielectric, ferroelectric and piezoelectric performances. Additionally, a comparative analysis of the crystalline and morphological behavior of the fabricated composite film with pure PVDF-TrFE films has also been reported. A maximum of 1.32 μC/cm2 saturated polarization and 0.604 μC/cm2 remnant polarization values are obtained for the composite film with a coercive field of ∼41 MV/m. The energy harvesting device fabricated from the CaZ/PVDF-TrFE composite film demonstrated an outstanding rectified output voltage of 3 V under continuous human hand tapping and performed well under an oscillating force, resulting in a peak to peak output voltage of 0.289 V at 0.5 N force. The proposed composite film-based device is expected to be a promising material for energy conversion and sensing in the futuristic energy generator applications.

用Ca掺杂的ZnO / PVDF-TrFE复合膜制造能量收集装置的方法

本文研究了一种基于Ca掺杂的ZnO(CaZ)纳米填料增强的聚偏二氟乙烯-三氟乙烯(PVDF-TrFE)复合膜的柔性压电能量收集装置,并证明了其具有增强的介电,铁电和压电性能。另外,还报道了用纯PVDF-TrFE膜对所制造的复合膜的结晶和形态行为的比较分析。饱和极化最大值为1.32μC/ cm 2且最大值为0.604μC/ cm 2对于矫顽场约为41 MV / m的复合薄膜,可获得剩余的极化值。由CaZ / PVDF-TrFE复合膜制成的能量采集装置在连续人手敲击下表现出出色的3 V整流输出电压,并且在振荡力下表现良好,在0.5 N时峰峰值输出电压为0.289 V力。预期所提出的基于复合膜的装置将是未来能源产生器应用中用于能量转换和传感的有前途的材料。
