| Research Abstract |
It is quite well known that physical properties of polymer are different from those of bulk state. In order to understand the singular physical properties of polymer thin films, we have studied the physical properties of polymer thin films both surface region and interfacial region by neutron reflectivity. As a result we found that the mobility near the surface region increased compared to that of bulk, on the other hand we also found that the mobility near the interfacial region drastically decreased compared to that of bulk. That is to say, the resulting physical properties of polymer thin film are determined by the counterbalance between surface effect and interfacial effect.
