Abstract: 
Novel random copolymers were synthesized by free-radical polymerization of a bicycloacry- late monomer carrying a fluorocarbon chain side group (BAF10) with a methacrylate monomer having a polysiloxane side graft (SiMA). The copolymers with higher contents of BAF10 gave rise to a well-ordered smectic bilayer mesophase. The surface structure of the derived polymer films was investigated by measurements of the contact angle with several interrogating liquids and X-ray photoelectron spectroscopy (XPS) at different photoemission angles. The values of the contact angles were used to evaluate the film surface tension, following different additive-component and equation-of- state methods. The low surface energies found were attributed to the pronounced hydrophobi- city and oleophobicity of the outermost surface caused by the preferential segregation of the fluorocarbon chains to the polymer-air interface. © 2009 WILEY-VCH Verlag GmbH & Co.
