Abstract :
Dielectric relaxation spectra of composite materials on the basis of natural and synthetic rubbers, LDPE filled with a ferroelectric ceramic powder PZT (lead zirconate titanate), the so-called 0-3 composites and polymeric blends were studied in this paper. Temperature-frequency dependencies of the complex permittivity were studied by using the dielectric spectroscopy method in frequency domain. The activation energy of polarization processes was estimated.
