Abstract

Semicrystalline polyethylene terephthalate (PET) film stacks were irradiated with 22 MeV/u Fe ions at room temperature under vacuum. Ion beam induced microscopic structural modifications and amorphous transformation were investigated by means of Fourier transform infrared spectrosocopy (FTIR), ultraviolet visible absorption spectrosocopy (UV/Vis) and Xray diffractometer (XRD). It was found that irradiation induces bond breaking, formation of new free radiculs and amorphous transformation. These effects were found to depend on ion fluence , the electronic energy loss and aborbed dose. The creation of alkyne groups was found only at the aborbed dose higher than 5.0 MGy.
