摘　　要：提出了一种基于双拱形结构的压电-摩擦复合纳米发电机的制备方法,利用锆钛酸铅（PZT）颗粒/碳纳米管（CNT）/聚二甲基硅氧烷（PDMS）形成的混合压电薄膜与铝电极作为压电层;利用倒模工艺形成带有均匀梯形体微结构的PDMS薄膜,与铝电极形成摩擦层,其中,中间铝电极为共享电极。同时,通过聚对苯二甲酸乙二醇酯（PET）膜实现双拱形结构,使压电层与摩擦层能够协同工作,提高输出电性能。研究结果表明,采用双拱形结构的复合纳米发电机,其压电单元的开路电压和短路电流值分别增加了52.7%和34.1%;摩擦单元的开路电压和短路电流值分别增加了75.2%和43.2%。压电单元和摩擦单元整流后混合输出的电能能够点亮10盏LED灯,存储在电容中能够为液晶显示屏（LCD）的正常工作提供电能。因此,该复合纳米发电机能够作为绿色能源供给器件被广泛应用。A fabrication method of a piezoelectric-triboelectric hybrid nanogenerator based on the double arched structure was presented.The piezoelectric layer was composed of the aluminum electrode and the hybrid piezoelectric film formed with PbZr0.52 Ti0.48 O3（PZT）particles,carbon nanotubes（CNTs）and polydimethylsiloxane（PDMS）.The triboelectric layer was made of the aluminum electrode and the PDMS film with the uniform trapezoid body micro-structures formed by the reverse mould technology.Among them,the middle aluminum electrode was the shared electrode.Meanwhile,the double arched structure was achieved by poly ethylene terephthalate（PET）film to realize the cooperative work between the piezoelectric layer and triboelectric layer and increase the output electrical performances.The study results show that for the hybrid nanogenerator with the double arched structure,the open-circuit voltage and short-circuit current of the piezoelectric unit increase by 52.7% and 34.1%,respectively.Correspondingly,the opencircuit voltage and short-circuit current of the triboelectric unit increase by 75.2% and 43.2%,respectively.The mixed output electrical energy of the rectified piezoelectric and triboelectric units can light up10 LED lights,and can be stored in the capacitors to provide the electrical energy for normal working of the liquid crystal display（LCD）.Therefore,the hybrid nanogenerator can be widely used as a green energy supply device.
