| 中文摘要 | previously, an inverted phase (the minority blocks comprising the continuum phase) was found in solution-cast block copolymer thin films. in this study, the effect of casting solvents on the formation of inverted phase has been studied. two block copolymers, poly(styrene-b-butadiene) (sb) (m-w = 73 930 da) and poly(styrene-b-butadiene-b-styrene) (sbs) (m-w = 140 000 da), with comparable block lengths and equal polystyrene (ps) weight fraction (similar to30 wt %) were used. the copolymer thin films were cast from different solvents, toluene, benzene, cyclohexane, and binary mixtures of benzene and cyclohexane. toluene and benzene are good solvents for both ps and pb, but have a preferential affinity for ps, while cyclohexane is a good solvent for pb but a theta solvent for ps (t-theta = 34.5 degreesc). the differential solvent affinity for ps and pb was estimated in terms of a difference between the polymer-solvent interaction parameter, chi, for each block. under an extremely slow solvent evaporation rate, the time-dependent phase behavior during such a solution-to-film process was examined by freeze-drying the samples at different stages, corresponding to different copolymer concentrations, rho. |
