摘要(Abstract)：

为了探究压电纳米发电机在给电子设备供电领域的应用潜力，提出一种在湿度变化的条件下通过静电纺丝法制备聚(偏氟乙烯-三氟乙烯)(P(VDF-TrFE))/钛酸钡(BaTiO₃)复合纳米压电薄膜的方法。利用扫描电镜、X射线衍射仪对压电薄膜进行表征，并以薄膜为基材制备纳米发电机，利用激振设备对其压电性能进行评估。激振实验表明，当纺丝环境相对湿度为65% 时，由P(VDF-TrFE)质量分数为10%、BaTiO₃质量分数为1% 的纺丝液制备的复合薄膜纳米发电机的压电响应输出最高，相较纯P(VDF-TrFE)提高了约2.0倍。实验表明，该纳米发电机可从日常运动中收集能量并为单片机供电，因此其在给低功耗电子设备供电领域具有较大的应用潜力。
