| Abstract: | The space charge storage stability ofporous polytetrafluoroethylene (PTFE) film s was studied and com paried with the solid PTFEfilm by m eans of the isotherm al surface potentialdecay and the open circuit therm ally stimulate discharge (TSD), etc. The shiftrule ofm ean chargedepth fortheporouselectretfilm wasinvestigated and then the charge transportation characteristic ofthe film was studied by TSD experim ent and therm alpulse technique. |
