| 摘 要： | 通过常温和高温下对ＰＶＤＦ／ＳｉＯ＿２，（ＰＶＤＦ－聚偏氯乙烯）膜的恒压负电晕充电，系统地研究了充电注入的负表面电荷受激脱阱后在电荷层自身内场作用下的输运规律。确定了ＴＳＤ（ＴｈｅｒｍａｌｌｙＳｔｉｍｕｌａｒｅｄＤｉｓｃｈａｒｇｅ）的偶极峰和空间电荷峰对电荷稳定性的明显区另。实验结果表明，高温负电晕充电对该材料的驻极性能有明显的改善。

| Abstract: | In this paper,the transport rule of detrapped negative surface charge under the self-field ofcharge layer is studied in detail by means of negative corona charging at room and elevated temperature forfilm PVDF/SiO_2.The a pparent differe nce for charge stability between dipole peak and space charge peak isdetermined by thermally stimulated discharge(TSD).The experimental results show that the properties ofthe electret PVDF/SiO_2 is im proved by negative corona charging at elevated temperature. |
