title: Nanodomain development of semifluorinated diblock copolymeric thin films via solvent vapor annealing.
abstract: The effect of solvent vapor annealing on the morphological change of poly(ethylene oxide)-b-poly(1H,1H dihydrofluorooctyl methacrylate) (PEO-b-PFOMA) micellar thin films has been studied. The time development of the nanodomain structure in PEO(5k)-b-PFOMA(10k) thin films was investigated with the vapor treatment of perfluoroalkanes. The block copolymeric thin film was initially cast from chloroform which is a good solvent for PEO. The as-cast film which has disordered morphology can be changed to ordered cylindrical morphology and at last to highly ordered morphology consisting of PEO spherical domains and PFOMA continuous phase by varying the annealing time.
