摘要
通过在常温和高温下对聚四氟乙烯(PTFE)薄膜的恒压电晕充电,讨论了热处理对PTFE驻极体电荷贮存性能的影响和该材料在高温下突出的电荷贮存能力.利用热脉冲技术和激光感应压力脉冲法(Laser Induced Pressure Pulse Method,LIPP)组合TSD(Thermally Stimulated Discharge)实验研究了PTFE脱阱电荷在电荷层自身场作用下的输运模型.
In this paper, the influence of heat-treatment on charge storage capability and the outstanding charge storage capability at elevated temperature for the PTFE electret were studied by means of constant voltage corona charging at RT and elevated temperature and the TSD experiment. The transport model of detrapping carriers of the PTFE electret which shifted towards the back electrode of the sample was investigated by means of the heat pulse technique, and the LIPP method in combination with the TSD experiment.
