The work is devoted to the fabrication and study of electret material based on cellulose diacetate polymer film with an intercalated active component, polar macromolecules Zn{(NH2)2CO}2Br2. The introduction of macromolecules into the film was carried out during its formation from solutions of various concentrations of cellulose diacetate and Zn{(NH2)2CO}2Br2 in tetrahydrofuran with ethyl alcohol under the action of a constant electric field of 2–4 kV cm–1. The temperature curves of the dielectric constant ε, the dielectric loss tangent tan δ, as well as the thermally stimulated depolarization currents j of the resulting films were determined. It was established that modification leads to the appearance of additional maxima in the ε(T), tan δ(T), and j(T) curves caused by the active component embedded in the film. Modification of a cellulose diacetate film causes an increase in the value of j and the surface charge density found from the j(T) curve by more than two orders of magnitude. The results obtained indicate the possibility of application of the method under consideration to fabricate electret films.
