| Outline of Final Research Achievements |
Soft materials, such as polymer gels and colloids, mainly consist of liquids. This aspect generates large internal freedom of the materials, which allows them to respond properly to tiny changes in the external environment. Thus, such soft materials can be candidates for so-called “smart materials”. However, most of the studies on soft materials have focused on polymers, and little attention has been paid to the liquid structures (the main component) and the changes in the liquid structures. In this study, the characteristic features of soft materials, typically autonomous structure formation, fluctuation, and transition (generalized as “autonomy”) are assumed to originate from the structure-forming properties of liquids. We have selected ionic liquids (ILs) as the structure-forming liquids for designing new soft materials. This study aims at understanding the effects of structure-forming properties and hierarchal structures of ILs on the autonomy of the resulting soft materials.
