Study of dielectric relaxation spectra of composite materials by the dielectric spectroscopy method

In this paper composite solid dielectrics were studied by using the dielectric spectroscopy method in frequency domain. Dielectric relaxation spectra of composite materials on the basis of natural and synthetic rubbers and LDPE filled with a ferroelectric ceramic powder PZT (lead zirconate titanate) were studied. The filled composites with high permittivity were used in HV insulation for the electric field control.
