| 中文摘要 | the effects of the molecular weights (molecular weight of polystyrene, m-w,m-ps, varying from 2.9 to 129 k) on the surface morphologies of spin-coated and annealed polystyrene/poly (methyl methacrylate) (ps/pmma = 50/50, w/w) blend films were investigated by atomic force microscopy and x-ray photoelectron spectroscopy. for the spin-coated films, when the m-w,m-ps varied from 2.9 to 129 k, three different kinds of surface morphologies (a nanophase-separated morphology, a pmma cellular or network-like morphology whose meshes filled with ps, a sea-island like morphology) were observed and their formation mechanisms are discussed, respectively. upon annealing, two different morphology-evolution processes were observed. it is found that a upper ps-rich phase layer is formed when m-w,m-ps < 4 k, and this behavior is mainly attributed to the low interfacial tension between ps and pmma component. when m-w,m-ps > 4 k, the ps-rich phase forms droplets on top of the pmma-rich phase layer which wets the siox substrate. these results indicate that the surface morphology of the polymer blend films can be controlled by the polymer molecular weight and annealing conditions. |
