采用静电纺丝法制备了一种新型柔性氧化锌/聚偏氟乙烯（ZnO/PVDF）纳米复合材料，并用于压电纳米发电机（PNG）的制备。以ZnO纳米粒子（NPs）和纳米棒（NRs）作为压电材料PVDF的纳米填料，制备了纤维状纳米复合膜。已经发现，压电ZnO NP和NR的添加可以改善用静电纺丝膜制造的PNGs的整体性能。ZnO NR/PVDF纤维膜基PNG（ZR-PNG）具有较高的电通量（开路电压约85 V，短路电流约2.2 μA），表明ZnO NR是PVDF的有效功能填料。氧化锌纳米棒的高纵横比和柔性特性被认为是非常有益的，为提高纳米复合材料的压电性能。ZnO纳米棒作为β相PVDF的成核剂，与复合纤维膜一起变形时也能产生压电电荷。已经得出结论，T…
A novel flexible zinc oxide/poly(vinylidene fluoride) (ZnO/PVDF) nanocomposite was prepared by electrospinning for fabricating a piezoelectric nanogenerator (PNG). The ZnO nanoparticles (NPs) and nanorods (NRs) were used as nanofillers of piezoelectric PVDF to prepare fibrous nanocomposite membranes. It has been found that the addition of piezoelectric ZnO NPs and NRs can improve the overall performance of the PNGs fabricated with the electrospun membranes. A large electrical throughput (open circuit voltage ∼85 V and short circuit current ∼2.2 μA) from the ZnO NR/PVDF fiber membrane-based PNG (ZR-PNG) indicates that ZnO NRs are effective functional fillers for PVDF. The high aspect ratio and flexibility characteristics of ZnO NRs were found to be highly beneficial for improving the piezoelectric properties of the nanocomposites. ZnO NRs act as nucleating agents of β-phase PVDF, and ZnO NRs can also produce piezoelectric charges when they deform with the composite fibrous membrane. It has been concluded t...
