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.
