| 中文摘要 | the thin films of poly(methyl methacrylate) (pmma), poly(styrene-co-acrylonitrile) (san) and their blends were prepared by means of spin-coating their corresponding solutions onto silicon wafers, followed by being annealed at different temperatures. the surface phase separations of pmma/san blends were characterized by virtue of atomic force microscopy (afm). by comparing the tapping mode afm (tm-afm) phase images of the pure components and their blends, surface phase separation mechanisms of the blends could be identified as the nucleation and growth mechanism or the spinodal decomposition mechanism. therefore, the phase diagram of the pmma/san system could be obtained by means of tm-afm. contact mode afm was also used to study the surface morphologies of all the samples and the phase separations of the blends occurred by the spinodal decomposition mechanism could be ascertained. moreover, x-ray photoelectron spectroscopy was used to characterize the chemical compositions on the surfaces of the samples and the miscibility principle of the pmma/san system was discussed. |
