Field of Specialization
Physical Properties of Polymers, Surface & Interfacial Sciences
Outline Activities
In general, surface and interface of polymeric materials are in a different energy state compared with the interior bulk region. Hence, structure and physical properties in the surface and interfacial region are supposed to differ from those in the corresponding bulk phase. The focus of our group is to understand the distinct feature of aggregation states and thermal molecular motion at surface and interface in polymer solid films by spectroscopy, ion-beam techniques, scattering experiments and microscopy. Recently, our group is also interested in photochemistry, leading to development of an interdisciplinary research field between polymer science and photochemistry.
