Study on Ar ion bombardment induced surface structural and compositional changes in PET
Semicrystalline polyethylene terephthalate (PET) film stacks were irradiated at room temperature with 35MeV/u Ar ions. Ion beam induced structural and compositional modifications were studied by means of X-ray diffractometer (XRD) and X-ray photoelectron spectroscopy (XPS) techniques. Significant amorphous transformation and chemical chain scissions were observed
which depended strongly on ion fluence and electronic energy loss near the sample surface. The chemical chain scissions were mainly found at carbonyl and methoxyl groups
which led to the relative decrease of amount of carbon and oxygen in these functional groups. The effects of amorphization and bond breaking increased with increase of ion fluence and electronic energy loss. The results were qualitatively discussed.
