摘要:
采用低温液相法合成了甲胺铅碘，并通过流延成型法制备了热塑性聚氨酯弹性体/甲胺铅碘复合薄膜，考察了复合薄膜的微观形貌、力学性能、介电性能、铁电性能和压电性能等，研究了基于该复合薄膜制备的纳米发电机的性能。结果表明，相比于纯热塑性聚氨酯弹性体，热塑性聚氨酯弹性体/甲胺铅碘复合薄膜的介电常数、剩余极化和压电性能均得到不同程度的提高，其中压电系数可达38 pC/N，超过了目前商用聚偏二氟乙烯压电薄膜的压电系数。基于热塑性聚氨酯弹性体/甲胺铅碘复合薄膜制备的压电纳米发电机的输出电压和电流分别达到了7.5 V和100 nA，可应用于人体能量收集和智能可穿戴传感器等领域。
Abstract:
Methylamine lead iodine was synthesized by low-temperature liquid phase method, and thermoplastic polyurethane elastomer/methylamine lead iodine composite films were prepared by tap casting method. The microstructure, mechanical properties, dielectric properties, ferroelectric pro-perties and piezoelectric properties of the composite films were investigated. The properties of nanoge-nerator based on the composite films were studied. The results showed that compared with pure thermoplastic polyurethane elastomer, the dielectric constant, residual polarization and piezoelectric properties of the thermoplastic polyurethane elastomer/methylamine lead iodine composite films were improved to various degrees. The piezoelectric coefficient could reach 38 pC/N, which had exceeded the current commercial polyvinylidene fluoride piezoelectric film. The output voltage and current of the piezoelectric nanogenerator based on the thermoplastic polyurethane elastomer/methylamine lead iodine composite films reached 7.5 V and 100 nA, respectively, which could be applied to human energy collection and intelligent wearable sensors.
