Abstract

The paper presents the results of polarization of PVDF films in glow, dielectric-barrier, and corona discharges. Measurements of the piezoelectric coefficient d33 showed that corona discharge had the highest polarization efficiency under the given processing conditions. A study of the samples by X-ray phase analysis and ATR IR spectrometry has shown that after polarization, the proportion of the piezoactive β-phase in the polymer increases, with its highest content being observed after corona treatment. It is noted that discharge treatment leads to a change in the wettability of the sample surface.
