Fluorination modification and electret properties were studied on the cellular polypropylene (PP) films modified by gaseous fluorine by attenuated total reflection (ATR) infrared analysis and the measurment of open-circuit thermally stimulated discharge (TSD) currentin situ TSD charge and isothermal charge decay. The results showed that the PP cellular filmsespecially the preoxidized onescan be effectively fluorinated by gaseous fluorineand that charge storage thermal stability of the fluorinated filmsespecially the fluorinated preoxidized onesis significantly improved compared with that of the virginal PP filmeven under conditions of negative pressure with a low partial pressure of gaseous fluorinelow reaction temperature about 60℃ and short reaction time of 15min.
