Space charge accumulation behavior in fluorinated polymer films irradiated by proton under DC stress

In this paper, proton irradiated fluorinated polymer films are investigated. Space charge distribution on such materials has been studied. It was shown that pristine materials do not accumulate charges under DC voltage application. On the contrary, positive charges were observed in irradiated films. Concerning this paper, we focused to introduce the space charge behavior under DC stress in the bulk of proton irradiated fluorinated polymers. Furthermore, we have also many experience of measurement and analysis of charge accumulation in the bulk of electron irradiated ETFE and FEP. Therefore, we also compared the effect of electron and proton irradiation for space charge accumulation behavior in ETFE and FEP.
