FIELD: manufacture of dielectric parts capable of keeping static charge for long time.
SUBSTANCE: proposed method for electret production includes condensation of vapors taken from controlled medium atmosphere on dielectric part whose resistance is over 1014 Ohm-cm to form condensate on part followed by drying the latter. Such method used for electret production makes it possible to eliminate changes in physical structure of polymeric part.
EFFECT: enhanced economic efficiency.
