Silica Colloidal Suspensions in Ionic Liquids: Colloidal Stability and Fabrication of Ion Gels on the basis of Colloidal Self-Assembly

摘要

On account of their remarkable physicochemical properties, ionic liquids are finding a wide range of applications as media for colloidal suspensions. However, colloidal stability in ionic liquids, determined by interactions between particles, is not well-understood. In this study, colloidal stability in ionic liquids was investigated using colloidal silica as a model colloid. Moreover, on the basis of the colloidal stability in ionic liquids, a functional soft material consisting of silica nanoparticles and an ionic liquid was fabricated.
