The aim of this work is the experimental and theoretical study of charge relaxation processes in the films of polyimide coated on both sides with lacquer PTFE (PMF-2), charged in a corona discharge at negative polarity in ambient conditions. The theoretical analysis is based on the model of quasi-continuous distribution of traps with respect to their energies. This paper shows that the stability of the electret state is caused by deep traps that are localized in a Teflon coating.
