Thermally Stimulated Discharge of UV-irradiated Corona-charged Teflon FEP Films
MetadataShow full item record
UV-irradiated Teflon FEP films, one side metalized and negatively corona charged, show peak shifts in their thermally stimulated discharge (TSD) curves as compared with those of unirradiated samples. They are practically discharged after the first TSD process, indicating that UV irradiation enables the contact to inject positive charge. Heat pulse records confirm positive injection from the UV irradiated contact. Positively charged films, UV irradiated, have a residual potential larger than the unirradiated ones and also show peaks shifts in their TSD thermograms. Results for both polarities are shown for different metallic contacts. © 1992 IEEE
