The electret properties of polystyrene composites with titanium dioxide have been studied. Optimal parameters were defined for manufacturing of corona electrets based on polystyrene. The introduction of 2–10 vol.% titanium dioxide to polystyrene resulted in better electret performances due to an increased portion of the polymer macromolecules with reduced mobility, appearance of interphase polarization and formation of high-energy traps at a polymer-filler interphase boundary. The thermal stability of the electret properties significantly increased for titanium dioxide-filled polystyrene.
