Abstract
Abstract In this work, polyethylene (PE) samples were subjected to 9 MeV Cl+2 ions with fluences ranging from 1 × 1013 to 5 × 1014 ion/cm2. Rutherford back scattering spectrometry (RBS), X-ray diffraction (XRD), ultraviolet–visible (UV–vis) spectroscopy and Vicker’s micro-hardness (Hv) techniques were used to investigate the compositional transformation, changes in the structure, optical and surface hardness of bombarded samples. The adhesion parameters were analyzed using the contact angle measurements. The obtained results showed that the ion irradiation caused a decrease in the crystallinity of polyethylene and increase in absorption of oxygen on the polymer surface as well. The absorption edge shifted towards the red shift as Cl-ion fluence increases. It was found that the hardness and adhesion parameters increase with increasing the ion beam fluence.
