The three major materials that support modern society are polymers, metals, and ceramics, of which we are working on polymeric materials in our laboratory. In order to improve the functionality and performance of polymeric materials, we are studying the hierarchical structures and formation mechanisms of polymeric materials from a microscopic viewpoint at the nanometer to micron scales, mainly using scattering methods (neutron scattering, X-ray scattering, light scattering) and microscopy methods (transmission electron microscope, scanning electron microscope, optical microscope). We are conducting basic research on soft matter. Specifically, we are investigating the self-assembled structure of block copolymers and its self-assembling processes, crystallization mechanism and higher-order structure formation of polymers, glass transition mechanism of polymers, hierarchical structure and formation mechanism of polymer gels, structure of polyelectrolyte solutions, dynamics and phase separation of polymer-constrained systems, and device development. As a future direction of basic research, we are aiming at the creation of soft matter science using quantum beams.
