Abstract
Synopsis: 3,4-Epoxycyclohexyl methyl methacrylate (M100) was polymerized by atom transfer radical polymerization (ATRP) using an initiator bound to fluorinated polyhedral oligomeric silsesquioxane (Rf-POSS). The polymerization proceeded in a living fashion, providing tadpole shaped polymers with an “inorganic head” of Rf-POSS and an “organic tail” of well-defined poly(3,4-epoxycyclohexyl methyl methacrylate). A hybrid film composed of the tadpole shaped polymer, cycloaliphatic epoxy resin (CEL2021P) and cationic initiator (SI－100) was cured at 160℃ for 1 hour, and then analyzed by contact angle measurement, X-ray photoelectron spectroscopy. These analyses revealed that the Rf-POSS was preferentially populated at the air/polymer interface and the outermost layer of the film was almost completely covered by the Rf-POSS heads. This was mainly due to the low surface free energy and environmental stability of the Rf-POSS moiety. The surface structure of the hybrid film was immobilized by cross-linking of epoxy resins, and the surface property was optimized by the control of curing condition.
