| Outline of Final Research Achievements |
Ionic liquids are expected to be applied to novel electrochemical and biofunctional devices due to their unique properties such as nonvolatile, nonflammable and high electric capacity. In this study, we visualized three dimensional solvation structures in aqueous solutions of a protic ionic liquid, Ethylammonium nitrate (EAN), and an aprotic ionic liquid, 1-Ethyl-3-methylimidazolium dicyanamide (emim-DCA) and revealed the relationship between the surface/solution properties and the solvation structures by ultra-low noise frequency-modulation atomic force microscopy (FM-AFM) with 3D-force mapping technique. In addition, we simulated the solvation structures by molecular dynamics technique and gained deep insight into the molecular structures.
