摘要
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(BaTiO_(3))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%、BaTiO_(3)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。
In order to explore the potential application of nanogenerators in supplying power to electronic equipment,poly(vinylidene fluoride-ethylene trifluoride)(P(VDF-TrFE))/Barium titanate(BaTiO_(3))composite piezoelectric films were prepared by high voltage electrospinning.Effects of ambient relative humidity in electrospinning were studied.The structure and properties of the membranes were analyzed by SEM and X-ray diffraction.The nanogenerators were prepared using the films as the substrates,and the piezoelectric effect of the nanogenerators was evaluated by vibration excitation.The experimental results show that when the relative humidity is 65%,the open-circuit voltage of piezoelectric nanogenerator based on the film prepared from dispersion containing 10%mass fraction of P(VDF-TrFE)and 1%mass fraction of BaTiO_(3) has the highest value,which is 2.0 times higher than that of pure P(VDF-TrFE).The study shows that the nanogenerator can harvest energy from daily motion and power up a microcontroller.Therefore,it has great potential for powering low-power electronic devices.
