Research Abstract

We found that ordered structures, such as multi-lamellar vesicles or charge-density-wave structures, are induced by an antagonistic salt (i.e., a salt composed of hydrophilic and hydrophobic ion pair) in a mixture of water and organic solvent. Furthermore, these mixtures show gel-like behaviors under flow. In this way, we confirmed that a mixture containing antagonistic salts shows the feature of polymers or surfactants even though it is composed of only low-molecular components.
