The Improvement of mechanical and gloss property by dual ion beam irradiation

Ion beam irradiation provides a unique way to modify the mechanical, optical, and the electrical properties of polymers by depositing the energy of ions in the material on an atomic scale. Beam irradiation of ions into polymers generally leads to radiation damage, which, in many cases, modifies the properties of the surface and the bulk of the material. These modifications result from changes in the chemical structure caused in their turn by changes in the chemical bonding when the incident ions cut the polymer chains, break covalent bonds, promote cross-linking, and liberate certain volatile species. The nature of these changes depends on the properties of the polymer, such as the composition and molecular weight. In this study, we measured the mechanical property changes of polymer surface such as hardness and strength. Also, we observed the change of gloss property before and after ion beam irradiation
