Abstract

Chemistry Chemistry, Multidisciplinary Crystallography Materials Science Materials Science, Multidisciplinary Physical Sciences Science & Technology Technology
Poly(ethylene oxide)-b-poly(1H,1H-dihydroperfluorooctyl methacrylate) (PEO-b-PFOMA) micellar films were cast from chloroform or alpha, alpha, alpha-trifluorotoluene (TFT) with different copolymer concentrations, followed by TFT or PF-5080 vapor treatment. Though their initial morphologies were different, finally the same patterns were obtained under TFT or PF-5080 vapor with varying the annealing time. The time dependent phase behavior was examined at different stages.
