摘要:

聚偏氟乙烯(PVDF)由于具有较大的压电响应和较高的热稳定性,一直被认为是一种理想的压电塑料。然而,压电PVDF元件的实现已被证明是有问题的,尤其是由于缺乏工业上可扩展的方法来将PVDF加工成适当的极性结晶形式。在这里,我们表明,完全压电PVDF薄膜可以通过一个单一的步骤过程,利用PVDF可以在低于其熔化温度的温度下成型,即通过固态加工。我们证明,我们从而产生d_PVDF,压电电荷系数的双轴拉伸的d_PVDF。我们预计,固态加工的简单性和可扩展性与我们PVDF结构的优异压电性能相结合,将为这种商品聚合物提供新的机会,并将为未来大规模工业生产塑料压电薄膜开辟一系列可能性

英文摘要:

Poly(vinylidene fluoride) (PVDF) has long been regarded as an ideal piezoelectric plastic because it exhibits a large piezoelectric response and a high thermal stability. However, the realization of piezoelectric PVDF elements has proven to be problematic, amongst others, due to the lack of industrially-scalable methods to process PVDF into the appropriate polar crystalline forms. Here, we show that fully piezoelectric PVDF films can be produced via a single-step process that exploits the fact that PVDF can be molded at temperatures below its melting temperature, i.e. via solid-state-processing. We demonstrate that we thereby produce d_PVDF, the piezoelectric charge coefficient of which is comparable to that of biaxially stretched d_PVDF. We expect that the simplicity and scalability of solid-state processing combined with the excellent piezoelectric properties of our PVDF structures will provide new opportunities for this commodity polymer and will open a range of possibilities for future, large-scale, industrial production of plastic piezoelectric films
