摘要
本文以四氟乙烯六氟丙烯共聚物（ＴｅｆｌｏｎＦＥＰ）医用驻极体薄膜为样品，通过等温表面电位裹减曲线和开路ＴＳＤ测量，研究０．９％ＮａＣｌ溶液对负电晕充电的ＴｅｆｌｏｎＦＥＰ驻极体的电荷储存稳定性的影响。研究结果表明：ＴｅｆｌｏｎＦＥＰ的电荷储存寿命明显地受０．９％ＮａＣｌ溶液的影响；热处理以ＴｅｆｉｏｎＦＥＰ的电荷储存寿命。
In this paper,the influence of 0.9%NaCl solution on cbarge storage Stability and the transportof detrapping charges in the bulk of Du Pont Teflon FEP film electret was investigated by isothermal surface po-tential decay decay and open-circuit TSD analysis.The experimental results indicated that the charge storage sta-bilitv of Teflon FEP materialis influenced by 0.9%NaCl solution.Heat treatment can improvethe charge storagestabili ty of Teflon FEP significantly.
