✦ Synopsis

The properties and the structure of polyethyleneterephthalate (PET) implanted with 150 keV Sb+ ions to the fluences of 1 x 1O"~l x 10'5cm-2 were studied using IR, UV-VIS spectroscopies and Rutherford back-scattering (RBS). The polymer surface layer 160G200nm thick was affected by ion implantation.

The results provide evidence for the occurrence of degradation processes in ion-exposed layers, including a Norrish II reaction and benzene ring scission. The concentration and the conjugation length of the double bonds produced by the degradation processes are an increasing function of the ion fluence. The measured temperature dependence of the sheet resistivity in the range 170-370 K confirms a variable hopping mechanism of the charge transport.
