Features of Thermally Stimulated Charge Storage and Relaxation in Heterogeneous Systems of Dispersed Mica

Abstract

Thermally stimulated spectra of hydrated dispersed mica in the range of temperatures (20–140)оС are analyzed to study the electret properties of the system subject to water content. It was found that electret and relaxation parameters of the samples depend on the amount of adsorbed water. Peculiarities of the electret state of mica particles low-dimensional system and the influence of adsorbed water on charge relaxation in the system have been established. Obtained results can be applied for developing new composite materials that contain dispersed mica as a filling compound.
