Organic-inorganic hybrid ferroelectrics are an exciting class of molecular materials with promising applications in the area of energy and electronics. The synthesis, ferroelectric and piezoelectric energy harvesting behavior of a 3d metal ion-containing A BX type organic-inorganic hybrid salt [Ph MeP] [Ni(NCS) ] (1) is now presented. P-E hysteresis loop studies on 1 show a remnant ferroelectric polarization value of 18.71 μC cm , at room temperature. Composite thermoplastic polyurethane (TPU) devices with 5, 10, 15 and 20 wt % compositions of 1 were prepared and employed for piezoelectric energy harvesting studies. A maximum output voltage of 19.29 V and a calculated power density value of 2.51 mW cm were observed for the 15 wt % 1-TPU device. The capacitor charging experiments on the 15 wt % 1-TPU composite device shows an excellent energy storage performance with the highest stored energies and measured charges of 198.8 μJ and 600 μC, respectively.
有机-无机杂化铁电体是一类令人兴奋的分子材料，在能源和电子领域有着广阔的应用前景。本文报道了一种含3d金属离子的ABX型有机-无机杂化盐[PhMeP][Ni(NCS)₄]（1）的合成、铁电和压电能量收集行为。对1的P-E回线研究表明，在室温下其剩余铁电极化值为18.71 μC/cm²。制备了含5%、10%、15%和20%（重量）1的复合热塑性聚氨酯（TPU）器件，并用于压电能量收集研究。对于含15%（重量）1的TPU器件，观察到最大输出电压为19.29 V，计算得到的功率密度值为2.51 mW/cm²。对含15%（重量）1的TPU复合器件进行的电容器充电实验显示出优异的能量存储性能，最高存储能量和测量电荷分别为198.8 μJ和600 μC。
