| 中文摘要 | phase separation of bisphenol a polycarbonate (pc) and poly(methyl methacrylate) (pmma) thin blend film is suppressed by addition of solid epoxy oligomer. epoxy has strong intermolecular interactions with both pc and pmma, while pc and pmma are quite incompatible with each other. consequently, phase separation in the pc/pmma blend film pushes epoxy to the interface; at the same time, pc and epoxy react readily at the interface to form a cross-linking structure, binding pmma chains together. therefore, the interface between pc and pmma is effectively reinforced, and the pc/pmma thin blend film is stabilized against phase separation. on the other hand, only an optimal content of epoxy (i.e., 10 wt %) can serve as an efficient interfacial agent. in contrast to the traditional reactive compatibilization, here we observed that the cross-linking structure along the interface is much more stable than block or graft copolymers. atomic force microscopy (afm) is used to characterize the morphological changes of the blend films as a function of annealing time. two-dimensional fast fourier transform (2d-fft) of afm data allows quantitative investigation of the scaling behavior of phase separation kinetics. |
