Abstract

Results are presented from studying the acoustic properties of polyvinylidene fluoride (PVDF) films of different thicknesses obtained using Langmuir‒Blodgett technology. The effect the number of monomolecular layers (10, 20, and 40 layers) and heat treatment have on the morphology of the resulting films is studied via atomic force microscopy. The existence of piezoelectric properties is demonstrated for films 40 layers thick. It is shown that additional polarization is not needed when obtaining Langmuir piezo-active PVDF films.

研究使用 Langmuir-Blodgett 技术获得的 PVDF 薄膜的结构和压电特性

摘要

结果是通过研究使用 Langmuir-Blodgett 技术获得的不同厚度的聚偏二氟乙烯 (PVDF) 薄膜的声学特性得出的。通过原子力显微镜研究了单分子层的数量（10、20 和 40 层）和热处理对所得薄膜形态的影响。40 层厚的薄膜证明了压电特性的存在。结果表明，在获得朗缪尔压电活性 PVDF 薄膜时不需要额外的极化。
