Coronoelectrets based on composites of polystyrene with a conductive filler – graphite – were studied. It was shown that the introduction of up to 8 vol% filler into the polymer raises the level and the time and thermal stability of its electret properties. By controlling the ratio of the components in the composite, it is possible to create electrets with prescribed properties.
