| Outline of Final Research Achievements |
Electrostatic interaction plays a dramatic role in ordering and structural formations of soft matter. We have shown an ordered lamellar structure is induced in a mixture of water and an organic solvent such as 3-methylpyridine by adding antagonistic salt composed of hydrophilic cation and hydrophobic anion. The heterogeneous distribution of cations and anions due to preferential salvation and the electrostatic interaction between these ions could be thought as the origin of the lamellar formation. Here we have investigated the effects of electrostatic interaction in soft matter such as liquids, surfactant membranes, polymers, Janus particles, liquid crystals, colloids, nano bubbles, and showed various aspects concerning the electrostatic interaction.
