中文摘要	the surface morphology evolution of three thin polystyrene (ps)/polymethyl methacrylate (pmma) blend films (<70 nm) on siox substrates upon annealing were investigated by atomic force microscopy (afm) and some interesting phenomena were observed. all the spin-coated ps/pmma blend films were not in thermodynamic equilibrium. for the 67.1 and the 27.2 nm ps/pmma blend films, owing to the low mobility of the pmma-rich phase layer at substrate surfaces and interfacial stabilization caused by long-range van der waals forces of the substrates, the long-lived metastable surface morphologies (the foam-like and the bicontinuous morphologies) were first observed. for the two-dimensional ultrathin ps/pmma blend film (16.3 nm), the discrete domains of the ps-rich phases upon the pmma-rich phase layer formed and the secondary phase separation occurred after a longer annealing time.
