| Outline of Final Research Achievements |
Physical properties, such as water solubility, viscosity, electrical conductivity, and thermal stability, of ionic liquids containing metal salts and/or water were investigated to discuss the solvation of metal ions in the pseudoternary ionic liquid - metal salt - water systems. Submicron-sized inverse micelles were found to be formed by the addition of trace water to ionic liquids containing metal ions. To achieve high-resolution imaging of the viscous ionic liquids / electrode interfaces, so-called solvation structures, a new class of FM-AFM system was developed by the introduction of a displacement sensing using optical interferometer and a novel sharpening process for silicon probes. Being inspired by the fact that, in ionic liquid media, water molecules act as neutral ligands, a series of ionic liquid-based baths containing neutral glymes were tried as metal electrodeposition baths. The use of glymes made the electrodeposition of Mg and Al possible at room temperatures.
