Abstract
Electric polarization of oriented PVC films was studied under conditio ns of over-breakdown electric fields and elevated temperatures. The ma ximum electric field strength E-p = 360 kV/mm was reached with the aid of a special low-conductivity spacer, which limited the leak current and prevented development of local breakdowns in the samples. Samples with high values of the residual polarization (P-r = 1.65 mu C/cm(2)) and piezoelectric modulus d(33) = 6-7 pC/N) were obtained.
