Research Subject
Control and design of molecular orientation and hierarchical structures towards developing high-performance soft materials

研究の背景 Background


Multiscale control and design of hierarchical structures, from a molecular orientation to a macroscopic structure, have attracted attention due to enabling the development of highly functional soft materials even with simple molecules. Understanding of stimuli-responsive behavior of soft materials in molecular-level and macroscale allows us to explore the potential of soft materials towards high-performance applications in the field of soft robotics, and micro-optics, etc.

研究の目標 Outcome


We aim to exploit a fundamental platform to develop highly functional soft materials with molecular-level to macroscopically controlled hierarchical structures. Through fabricating advanced sensing materials and/or techniques, we try to reveal the relations between molecular-level ordered structures such as molecular orientation and macroscopic materials performance.
