An Experimental Consideration on the Decay of Surface Potential from Corona Charged Polysulfone Films |
| Abstract |
Both of the isother mally and thermally stimulated surface potential decay characteristics(SPDC) have been investigated not only in corona charged polysulfone(PSF) which is one of heat resistant polymer, but also in corona charged polyethyleneterephthalate(PET) and polyfluoroethylene propylene(Teflon FEP) under the same experimental condition. PSF and PET shows similar SPDC in the high teperature region. Also the effect of polarity on SPDC observed from PSF and Teflon FEP shows almost the same phenomenon. From these results, we suggest that the mechanism on SPDC of PSF could be explained as the bulk conductivity from the characteristic analysis concerning PET and electron affivity from characteristic analysis concerning Teflon FEP. |
