Modification of Polyethyleneterephtalate by Implantation of Nitrogen Ions

Abstract

The implantation of 90 keV N+ ions into polyethyleneterephtalate (PET) to fluences of was studied. The changes in electrical sheet conductivity and polarity of ion‐exposed PET were observed and the structural changes were examined using IR spectroscopy. One degradation process is a chain fission according to the Norrish II reaction. The sheet conductivity due to conjugated double bonds was increased by ten orders of magnitude as a result of ion implantation. The surface polarity of the PET samples increases slightly with increasing ion fluence.
