摘　　要：本文利用电化学沉积法在PET-ITO柔性基底上成功制备出ZnO纳米发电机。采用X射线衍射仪,扫描电子显微镜和电化学工作站对ZnO纳米棒进行了生长观察和性能测试。XRD图谱显示,在不同沉积时间下ZnO纳米棒都具有(002)峰的择优取向。SEM表面形貌图显示,电沉积时间为2h时ZnO纳米棒呈现明显的六角纤锌矿结构。SEM断面图表明,电化学沉积2h的纳米棒最长为1.1μm。为了更好地观察不同沉积时间对纳米发电机的性能影响,在沉积时间为1,1.5,2h的条件下制备了3种纳米发电机。最终结果显示,电沉积时间2h制备的纳米发电机的电压输出性能最好,输出电压为960mV。最后,研究了电沉积法制作纳米发电机的工作机制。In the present study,ZnO nanogenerators were fabricated on PET-ITO flexible substrates by electrochemical deposition.The ZnO nanorods were examined using an X-ray diffractometer,a scanning electron microscope,and an electrochemical workstation.The results show that the ZnO nanorods exhibit a preferred orientation of the(002)peak that varies with the deposition time.SEM images show that the ZnO nanorods that were electrodeposited in under 2 h exhibit a significant hexagonal wurtzite structure.SEM cross-sectional images of these ZnO nanorods show that they have a length of up to 1.1μm.To better observe the piezoelectric properties of nano-generators for which the ZnO nanorods were deposited over different durations,three different types of nano-generator were prepared.The results show that the nanogenerator with the ZnO nanorods that were deposited in under 2 h has an output voltage of 960 mV.In addition,this paper explains the working mechanism of a nano-generator prepared using the electrodeposition method.
