针对驻极体微型化后存在表面电位低和稳定性差等诸多问题,通过对充电电压、温度、湿度和时间等充电过程参数和微型化驻极体的制备方式的一系列对比实验和分析,获得了Teflon驻极体的优化充电条件,得到了较高表面电位和稳定性好的微型化Teflon驻极体。

英文摘要：

Aimed at solving the problems, such as low surface potential, unstable etc, of the micro-electret, we structured the Teflon electret charge experimental platform, based on the study of the parameters of charging, such as the charging voltage, temperature, humidity and time, got a higher surface potential and stability of the good performance of miniaturization Teflon electret. Summing up some certain micromation methods and charging conditions to gain high-performance micro-electret （Teflon electret）. Provide refer- ence to the application of micro-electret.
