聚偏氟乙烯(PVDF)的压电效应近年来引起了人们的极大兴趣,用它制成的各种换能器已得到了广泛应用,关于它的压电性及其分子运动已有报道。为了探索PVDF共混体系中第二组分对薄膜压电性能的影响及开发新的压电材料,我们研究了PVDF的三个共混体系的压电性及其分子运动。这三个共混体系是:
The piezoelectric effect of polyvinylidene fluoride (PVDF) has drawn great interest in recent years. Various transducers made of it have been widely used, and its piezoelectricity and molecular motions have been reported . In order to explore the influence of the second component on the piezoelectric properties of PVDF blends and to develop new piezoelectric materials, we investigated the piezoelectricity and molecular motion of the three blends of PVDF. These three blends are:
