Abstract

The paper presents the results of PVDF film polarization in glow, barrier and corona discharges. Measurements of the piezoelectric coefficient d33 showed that the highest polarization efficiency under the selected process conditions is observed in the corona discharge. The study of samples by X-ray phase analysis and ATR-FTIR spectroscopy showed that after polarization, the proportion of piezoactive β-phase increases in the polymer, the highest content of which is observed after treatment in a corona discharge. It is noted that treatment in a discharge leads to a change in the wettability of the sample surface.
