摘要

本文初步比较了聚偏氟乙烯静电纺纳米纤维膜与工业聚偏氟乙烯薄膜的压电性能。XRD测试结果表明，静电纺PVdF膜的β相比本文所考虑的PVdF膜的β相大得多。因此，纳米纤维膜显示出与施加在样品上的机械脉冲应力相关的电响应的显著增加，相对于薄膜样品提供的电响应。特别是，纳米纤维样品的单位重量的电信号要大得多，即比商业平面样品大几个数量级。这种行为可能会引起人们的兴趣，例如，在冲击传感器和能量收集领域。

Electrospun nanofibers with piezoelectric properties

This paper presents a preliminary comparison between the piezoelectric behavior of PVdF electrospun nanofibrous membranes and a commercial PVdF film. XRD measurements showed that the β phase of the realized electrospun PVdF membranes is much larger than that of the PVdF film here considered. Consequently, the nanofibrous membranes show a significant increase of the electrical response associated with a mechanical impulsive stress applied to the sample, with respect to that provided by film specimens. In particular, the electric signal per unit weight is much larger for the nanofibrous specimens, i.e. a few orders of magnitude larger than that of commercial flat specimens. This behavior could be of interest, e.g, in the field of impact sensors and energy harvesting.
