| Research Abstract |
The structures and properties of polymer monolayers were studied by atomic force microscopy (AFM) in order to understand the two-dimensional (2D) ultimate structures of polymer soft-interfaces. In this study, (1) we succeeded to observe the melting behaviors of 2D crystals in situ at the molecular level, and found the significant melting temperature depression up to 90℃. (2) We also succeeded to visualize the isolated chains of a polymer of a high glass transition temperature (Tg) solubilized in a monolayer of alow Tg polymer, and evaluated the chain conformations in the 2D monolayer. (3) We also found that a blend monolayer phase separated via 2D spinodal decomposition mechanism for the first time. (4) Polymer isolated chains deposited on a substrate were observed in situ at temperature much higher than the bulk Tg of the polymers. (5) Vapor phase deposition polymerization on mica was also studied by AFM.
