Electret effect in heterogeneous systems comprising low-dimensional particles with electrically active surface

Experimental and theoretical investigations of the electret effect in low-dimensional micas with different degrees of dispersion and adsorption are carried out at temperatures in the range 20–140°C. The results obtained allow the electric activity of the mica particles comprised in these systems to be determined and the efficiency of application of low-dimensional micas for fillers of composite materials to be estimated.
