Abstract

A series of diblock copolymers prepared from styrenic monomers was synthesized using ATRP. One block was derived from styrene while the second block was prepared from a styrene modified with an amphiphilic PEGylated-fluoroalkyl side chain. The surface properties of the resulting polymer films were carefully characterized using dynamic contact angle, XPS and NEXAFS measurements. The polymer morphology was investigated using AFM and GISAXS studies. The block copolymers possess surfaces dominated by the fluorinated unit in the dry state and a distinct phase separated microstructure in the thin film. The microstructure of these polymers is strongly influenced by the thin film structure in which it is investigated.
