The microphase separated structure of amphiphilic block copolymers have been widely studied in solution, bulk, as well as in thin film. We have successfully synthesized amphiphilic block copolymers consisting of water-soluble poly [tri(ethylene glycol) methyl ether methacrylate] (PM3) and polystyrene. Interestingly, the polar PM3 segment selectively segregated on the top of the surface layer under dry conditions in the amphiphilic block copolymer thin film, in spite of its hydrophilic character. In this presentation, to evaluate the surface energy of PM3, we synthesized a novel series of well-defined amphiphilic block copolymers containing PM3 and polyisoprene (PIsp) or polydimethylsiloxane (PDMS) by means of living anionic polymerization and analyzed the surface structure of their thin films by X-ray photoelectron spectroscopy, scanning electron microscopy (SEM), and atomic force microscopy (AFM) measurements.
