Abstract
Electron beam radiation effects of PET have been investigated. Microstructural changes in poly(ethylene terephthalate) subjected to electron beam irradiation at doses of 50kGy, 100kGy, 200kGy, 400kGy were investigated by Attenuated total reflectance infrared spectroscopy (ATR-FTIR), X-ray diffraction (XRD) , Atomic force microscopy (AFM) and scanning electron microscopy (SEM). Irradiated samples showed a increase of crystallinity with a minimum at 200kGy, which is attributed to secondary crystal and then an decrease at further doses due to some degradation effect. The chemical structure and surface topography has only a slight change with irradiation.
