摘要 本文首次根据栅控恒压电晕充电组合反极性电晕补偿充电法的实验结果计算出电晕极化的PVDF铁电聚合物驻极体的极化强度。实验结果说明:PVDF铁电聚合物驻极体在180MV／m极化电场下可能形成约35mC／m2的高极化强度。电晕充电组合反极性电晕补偿充电法是研究极性驻极体材料电极化的一种有效方法。 In this paper, polarization of the ferroelectric polymer electret PVDF formed by corona charging is firstly estimated based on the experimental results of charging current in the corona charging with a grid in combination with the reverse-polarity corona charging compensation method. The experimental results show that up to 35mC/ m2 of high polarization for the ferroelectric polymer of PVDF is obtained under the poling field of 180MV/m. The corona charging in combination with the reverse-polarity corona charging compensation method is valuable in the study of the electrical polarization of polar polymer.
