Research Summary

Yasuhiro  Ishida(D.Eng.)

Our team aims to create water-based materials, referred to as aqua materials, as replacements for conventional plastics. Taking advantage of their unique properties as moldable, portable water, together with the elaboration of their inner or surface parts, we will demonstrate their various applications as intelligent soft materials. We are employing a wide range of chemicals as the components of aqua materials, in order to improve their properties and to ultimately realize environment-conscious materials. Our challenge also includes the rational design of novel bio-inspired materials, by assembling molecules with dynamic and static functions within aqua materials used as scaffolds.
