Effect of Ion beam irradiation on the Physical and Chemical Properties of plasticized poly ethylene terephthalate (PET) polymer used in Medical Device [ ]

Ion beams have been found to be widely applicable in improving the structure and physical properties of polymers. In this paper, the effect of ion bombardment on physical and chemical properties of plasticized poly ethylene terephthalate (PET) was studied. Polymer samples were bombarded with 3 keV Ar ions to fluencies ranging from 2.8125 x 10 17 to 5.625 x 10 17 ions cm−2. The pristine and ion beam bombarded samples were investigated using TGA thermal Analyzer and FTIR spectroscopy, PET were evidently changed after irradiation. Ionizing radiations always have a large effect on the physical properties of polymers. The thermal stability of PET at various ion fluencies was illustrated increase from 439.65 to 442.88°C the pristine sample and those samples bombarded with Ar ion at the highest fluence.
