Improving the Thermal Stability of the Electret Properties of Corona Electrets Based on Fluoroplastic-32L

摘要

Corona electrets based on composites constituted by fluoroplastic-32L and powdered ferroelectric filler, barium titanate, were studied. It was found that introduction of a ferroelectric filler into fluoroplastic-32L improves the thermal stability of the electret properties by 30-40°.
