A comparative study has been carried out of the electret properties of PET film before and after the effect of aerosol particles (AP). Those properties have been shown to depend not only on the nature and the method of polymer polarization but also on the change of their micro- and permolecular structure (PMS). The spectrum analysis of thermo- stimulated depolarization current has revealed singularities of differences of relaxation of stabilized electrets charges in bulk and on the near-surface layers of PET films. The thus-obtained data on the change of relaxation properties of elec- trets of PET films allow us to say that it is possible to use these films so as to make economical and fit for use aerosol catchers of different purposes and sensitive sensors based on the principle of the decrease of value of electret charges.
