英文摘要	Investigation of the surface modification in molecular structure of semicrystalline polyethylene terephthalate (PET) films induced by Ar ion bombardment is presented. The PET samples are analysed by using Fourier transform infrared spectroscopy (FTIR), X-ray diffractometer (XRD), and X-ray photoelectron spectroscopy (XPS). A significant loss of crystallinity is observed, which is related to the configuration transformation of ethylene glycol residue from the trans into the gauche. Chain scissions are observed at the para position of di-substituted benzene rings, -C=O bonds and C-O bonds. The C-O bonds are destroyed more selectively than -C=O bonds. The benzene ring structures show only small change under irradiation and do not participate in degradation process. Extra C=C bonds and alkyne end groups are created above a critical dose of 4.0 MGy. The results are briefly discussed. (C) 2000 Elsevier Science B.V. All rights reserved.
