 The study results of the charge relaxation mechanisms in composite polylactide based fi lms with hydrophilic nanodispersed fi llers are presented. It is shown that the charge-dipole centers act both as polar structures involved in creating the electret state and as trapping centers for charge carriers in the initial polylactide fi lms. It is established that deep traps for the injected charge carriers are inherent in the initial PLA fi lms (deep traps are not created by the added fi ller). The stability of the electret state in PLA-based fi lms is determined by the polymer matrix of the materials under study.
Keywords: polylactide, biodegradable active packaging, coronoelectret, thermoelectret,
unipolar conductivity, charge-dipole complex, the stability of the electret state.
