Depolarization currents in polyvinylidene fluoride caused by relaxation of charge and polarization
Department of Physics and Material Science, Odessa National Academy of Food Technologies, ul. Kanatnaya 112, 65039 Odessa, Ukraine
The procedure has been developed for extracting homocharge and heterocharge currents from experimentally measured thermally stimulated depolarization currents of corona poled PVDF. application of different depolarization modes supplemented with the isothermal currents allowed to obtain such parameters of the relaxation processes, as activation energies, characteristic frequencies and time constants.
Key words: polymer ferroelectrics, homocharge, heterocharge, depolarization.
