| Research Abstract |
Poly(methyl methacrylate)(PMMA)/poly(n-nonyl acrylate) blend monolayer was a miscible system, and if a small amount of PMMA chains was solubilized in a PNA monolayer, the isolated PMMA chains in the PNA monolayer were, for the first time, successfully visualized by atomic force microscopy. The radius of gyration of the PMMA chain solubilized in the PNA monolayer scaled with the PMMA molecular weight in a power of 0.63, but was independent on the molecular weight of the matrix PNA over a wide range. These results indicate that the PNA/PMMA monolayer is a strongly miscible system, although the scaling, 0.63 with the PMMA molecular weight is slightly smaller than the value for two-dimensional good solvent system (0.75).
