| Outline of Final Research Achievements |
Up to now, the spreading process of polymer melt on a solid substrate is one of the unsolved problem. In order to understand this mechanism, the molecular visualization of isolated polymer chain under flow is needed. In this study, spreading of a poly(methyl methacrylate)(PMMA)/PMMA oligomer blend, which was a miscible system, on a mica substrate is observed by using in-situ atomic force microscopy(AFM) under constant temperature and humidity to investigate the mobility of an isolated polymer chain under flow. The results showed that the isolated PMMA chain in PMMA/PMMA oligomer blend under flow were successfully visualized with molecular resolution by AFM. This study is very important to understand the surface phenomenon, such as adhesion, wetting and friction.
