Change the world and our lives with soft materials!

We are researching soft materials which can be applied to a wide area around our lives. Our lab especially focuses on supramolecular systems and block copolymers such as slide-ring materials, necklace-like polyrotaxane, nanocellular structures, and surface segregation of hydrophilic block copolymers, which form fascinating structures self-assembly. They do not only bring a new science and technology in polymeric materials but can be applied to scratch resist coating, soft actuator, heat insulator, surface reforming, and so on. Some of them were available on the market already. Actually, I founded a venture company to promote various applications and businesses based on the novel concept of polymeric materials. I believe that our research will change the world and our lives drastically.

Message to students

You can find a lot of fascinating systems in soft materials. I suppose that our lab is featured by an academic fusion between chemists and physicists, and a close balance between basic science and applied technology. If you are interested in chemistry or physics of soft materials, please come and join us!

Introduction of the study

Introduction of the study

Polymers, liquid crystals, colloids, and membranes have a common feature such as softness, large fluctuation and response to external stimuli, and complex hierarchical structures. Therefore, they are classified as soft matters or soft materials. Of them, our current research topics include slide-ring materials with freely movable cross-links, structure and dynamics of supramolecular polyrotaxane, spontaneous segregation of hydrophilic block copolymers, and nanocellular structures formed with supercritical carbon oxide. We are interested in both chemistry and physics of these polymeric materials and actually cover a wide range of research on them: synthesis of molecules, measurement of mechanical, electrical, optical, thermal properties, theoretical analysis, and even practical application.
