| 中文摘要 | we have followed the time development of the microdomain structure in symmetric diblock copolymer poly(styrene-b-methyl methacrylate), p(s-b-mma), ultrathin films via pmma-selective solvent vapor treatment by atomic force microscopy (afm). after preparation on a substrate preferentially attracting the pmma block, ps forms a continuous layer at a film's free surface. with subsequent solvent vapor treatment, the film gradually shows a well-ordered hexagonally packed nanocylinders structure. it is shown that only when the film thickness is less than the 1/2l(0) (lamellar repeat spacing), and exposed to pmma block selective solvent for an appropriate time, can the well-ordered hexagonally packed nanocylinders form. on an extended solvent vapor treatment, a mixed morphology containing nanocylinders and stripes appears, followed by the striped morphologies. when the annealing time is long enough, the film comes back to the flat surface again, however, with pmma instead of ps dominating the free surface. |
