Abstract: Abstract Contact angles of water and methylene iodide were measured as a function of UV/O3 treatment time for three polymers: poly(methyl methacrylate) (PMMA), polycarbonate, and polytetrafluoroethylene (PTFE). Surface roughnesses were also measured. Surface free energies were then calculated using relationships developed by Kaelble and Neumann. The surface energy of polycarbonate was found to increase (∼ 60%) during UV/O3 treatment. However, calculations on PMMA were hampered by the formation of a water solu…
