Outline of Final Research Achievements

Polymers are generally composed of long flexible chains, and the structures and dynamics of these flexible chains determine the properties of polymer materials. Using atomic force microscopy (AFM), movements of isolated polymer chains on substrates have been observed at a molecular level, however, those in aggregates such as solids or melts have not been visualized, yet. In this work, we visualized movements of isolated chains solubilized in Langmuir-Blodgett (LB) films under high humidity, and found that the movements of the chains were strongly affected by the nature of matrix polymers. We also successfully observed the formation of a stereocomplex from isolated chains which were solubilized in LB films.
