Corona electrets based on compositions of polypropylene and Aerosil A-200 were studied. Revealed that the polypropylene composition with aerosil have increased electret characteristics, in contrast to unfilled PP, due to the advent of the new system of energy traps. Best electret properties are compositions containing 6% Aerosil. Introduction of aerosil in polypropylene leads to higher thermal stability of electret properties to 20-40 º C.
