| 中文摘要 | the surface morphologies of poly(styrene-b-4vinylpyridine) (ps-b-p4vp) diblock copolymer and homopolystyrene (hps) binary blend thin films were investigated by atomic force microscopy as a function of total volume fraction of ps (phi(ps)) in the mixture. it was found that when hps was added into symmetric ps-b-p4vp diblock copolymers, the surface morphology of this diblock copolymer was changed to a certain degree. with phi(ps) increasing at first, hps was solubilized into the corresponding domains of block copolymer and formed cylinders. moreover, the more solubilized the hps, the more cylinders exist. however, when the limit was reached, excessive hps tended to separate from the domains independently instead of solubilizing into the corresponding domains any longer, that is, a macrophase separation occurred. a model describing transitions of these morphologies with an increase in phi(ps) is proposed. the effect of composition on the phase morphology of blend films when graphite is used as a substrate is also investigated. |
