摘要

通过静电纺丝技术制备聚偏氟乙烯三氟乙烯和氧化锌(P(VDF-TrFE)/ZnO)复合膜作为柔性摩擦电压力传感器的核心层．探究了氧化锌掺杂量对压电性能的影响，场发射扫描电镜(FE-SEM)结果显示氧化锌的分散较为均匀，纳米纤维的平均直径约为425 nm，并呈现有序排列．傅里叶变换红外光谱仪(FT-IR)结果显示，846、1 275、1 451 cm-1处的吸收峰证实铁电β相的存在．采用X射线衍射(XRD)测定了薄膜晶相，2θ=20.1°处的衍射峰对应P(VDF-TrFE)的β相．氧化锌掺杂量为5、10、15、20 wt%的P(VDF-TrFE)/ZnO的摩擦电压力传感器，其输出电压分别为0.55、1.10、1.50、2.70V．对掺杂量为20 wt%的P(VDF-TrFE)/ZnO器件做冲压及稳定性测试，经过1 200次循环测试后，摩擦电压力传感器的输出电压仍为2.70 V，基本保持不变，表明该器件具有较好的机械耐久性．

Abstract

P(VDF-TrFE)/ZnO composite film was prepared by electrospinning technology as the core layer of flexible triboelectric pressure sensor. P(VDF-TrFE)/ZnO composite films with different zinc oxide doping amounts were prepared. The surface morphology of each component film was observed by field emission scanning electron microscopy(FE-SEM). The results show that the dispersion of zinc oxide is more uniform and the average diameter of the nanofibers is about 425 nm

and nanofibers are arranged in order. The composition of the film was determined by Fourier transform infrared spectrometer(FT-IR)

and the existence of ferroelectric β phase is verified at the absorption peaks of 846

1 275 and 1 451 cm-1. The crystal phase of the film was determined by X-ray diffraction(XRD). The diffraction peak at 2θ = 20.1° corresponds to the β phase of P(VDF-TrFE). The output voltage of the P(VDF-TrFE)/ZnO triboelectric pressure sensor with 5

15 and 20 wt% doping amount is 0.55

1.10

1.50 and 2.70 V

respectively

which shows that the output voltage increases with the increase of ZnO doping amount.Stamping and stability tests were performed on the P(VDF-TrFE)/ZnO device with a doping amount of 20 wt%.After 1 200 cycles of testing

the output voltage of the triboelectric pressure sensor is still 2.70 V

and the result remains basically unchanged

indicating the device has good mechanical durability.
