    Abstract

    The stability of carbon dioxide (CO2) plasma treated polyethylene (PE) surfaces was studied. Reorganization processes on the oxidized surfaces were investigated using XPS and dynamic contact angle measurements. It was found that the restructuring phenomena at the surface is due to rotational and small segmental motions that minimize the free energy of these thermodynamically unstable surfaces. These motions also cause a decrease in wettability of the surface. The surface also stabilizes by sending its segments with functional groups into the bulk of the polymer, thus increasing the entropy of the system.
