本文介绍了聚偏氟乙烯(PVDF)-Zn2GeO4 （ZGO）细纤维垫的研制与表征。采用水热法合成了ZGO纳米棒，并将其掺入PVDF溶液中制备了细纤维垫。通过改变ZGO nr的浓度（1.25-10 wt %），采用强制旋切(R)法制备纤维垫。发育的垫子显示出长、连续和均匀的纤维，平均纤维直径在0.7到1 μ m之间，这取决于ZGO的浓度。x射线衍射谱显示了ZGO核磁共振的浓度与PVDF纤维内β相的增强呈正相关。含有1.25 wt % ZGO的复合材料系统显示出最高的压电响应，为172 V。这种细纤维复合材料系统在能量收集和为可穿戴和便携式电子设备供电方面具有潜在的应用前景。
The current paper presents the development and characterization of polyvinylidene fluoride (PVDF)-Zn2GeO4 (ZGO) fine fiber mats. ZGO nanorods (NRs) were synthesized using a hydrothermal method and incorporated in a PVDF solution to produce fine fiber mats. The fiber mats were prepared by varying the concentration of ZGO NRs (1.25-10 wt %) using the Forcespinning(R) method. The developed mats showed long, continuous, and homogeneous fibers, with average fiber diameters varying from 0.7 to 1 mu m, depending on the ZGO concentration. X-ray diffraction spectra depicted a positive correlation among concentration of ZGO NRs and strengthening of the beta phase within the PVDF fibers. The composite system containing 1.25 wt % of ZGO displayed the highest piezoelectric response of 172 V. This fine fiber composite system has promising potential applications for energy harvesting and the powering of wearable and portable electronics.
