The electret properties of polyethylene films with nanodimensional particles of talc have been investigated. The stable of electret state of polyethylene was improved with the addition of talc. This result can be explained by the fact that hydroxyl groups, which absorbs water, are locate on the peripheral area of talc particles. Accordingly, number water molecules in the polymer volume become less, and, therefore, the conductivity of a material should be decrease, and the stability of the electrets state should be increase. The adding of talc in polyethylene leads to a new relaxation process, that it is visible on the spectra thermally stimulated depolarization. The peak in this area can be associated with the process of accumulation and relaxation of charge on the border of phases of polymer-filler.
