Abstract
Novel fluorinated organic－inorganic hybrid polymers, poly (methylmethacrylate-co-methacryroxypropyl (trifl uoropropyl-T8-silsesquioxane))s [poly(MMA-co-7F-T8-MMA)], were prepared from fl uorinated polyhedral oligomeric silsesquioxane (F-POSS) derivative monomer aiming for the application for surface modifi cation of polymeric materials. A blend material composed of poly (MMA-co-7F-T8-MMA), a multi-functional acrylic monomer and radical photo initiator was cured by ultraviolet radiation. The resulting polymer films were analyzed by contact angle measurement, X-ray photoelectron spectroscopy, atomic force microscopy and field emission scanning electron microscopy. These analyses revealed that the F-POSS was preferentially populated at the air/polymer interface and that the outermost layer of the fi lm was almost completely covered by the F-POSS side-chains. This was mainly due to the low surface free energy and environmental stability of the F-POSS moiety.
