Description
Summary:The electret properties of polystyrene composites with titanium dioxide were studied. The optimal parameters were defined for manufacturing corona electrets based on polystyrene. The introduction of 2–10 vol % titanium dioxide into polystyrene resulted in better electret performance owing to an increased portion of polymer macromolecules with a reduced mobility, the appearance of interphase polarization, and the formation of high-energy traps at the polymer–filler interphase boundary. It was shown that the thermal stability of the electret properties significantly increased for the polystyrene filled with titanium dioxide.
