Abstract

The effects of Polytetrafluoroethylene (PTFE) thickness, charging temperature, and annealing treatments on electrostatic surface potential (ESP) stability and charge decay mechanism of corona charged PTFE electret films studied. The ESP stability were studied by isothermal surface potential decay at 90 ± 1 °C. The initial surface potential was found proportional to thickness, charging conditions, and annealing treatments. Annealing treatments before and after the charging process at 220 ± 1 °C enhanced the ESP stability of electret films by 20–25 % under room environmental conditions. Upon improving the ESP stability of PTFE electret films, electret dosimeters with different sensitivity ranges and practical performance have been produced.

电晕带电聚四氟乙烯驻极体膜的静电表面电位稳定性及辐射防护剂量学的一些参数优化

研究了聚四氟乙烯（PTFE）厚度、充电温度和退火处理对电晕带电PTFE驻极体膜静电表面电位（ESP）稳定性和电荷衰减机理的影响。采用90±1℃等温表面电位衰减法研究了电潜电的稳定性。发现初始表面电位与厚度、充电条件和退火处理成正比。在220±1℃下进行充电前后的退火处理，使驻极体膜在室温条件下的ESP稳定性提高了20 - 25%。在提高聚四氟乙烯驻极体膜ESP稳定性的基础上，研制出了具有不同灵敏度范围和实用性能的驻极体剂量计。
