| Outline of Final Research Achievements |
The behavior of a polymer melt spreading on a substrate is not well-understood at present. If we could observe the spreading behavior of the droplet by atomic force microscopy (AFM) at the molecular level, our understanding of polymer surface phenomena will be significantly improved. In this study, we observed the precursor film formed ahead of a spreading droplet of an isotactic poly(methyl methacrylate)(it-PMMA)/oligo (MMA) blend on mica in situ in real time. We successfully observed it-PMMA chains flowing in the precursor film. The spreading behavior of the droplet and the it-PMMA molecules flowing in the precursor film was strongly affected by humidity.
