The goal of this project is to understand the intermolecular forces that promote amphiphile self assembly in ethylammonium nitrate (EAN), a room temperature ionic liquid (IL). In previous work using SANDALS we have demonstrated that EAN has pronounced sponge-like nanostructure, and SANS experiments have shown that EAN facilitates the formation of conventionally structured micelles. Open to question is the mechanism by which EAN imparts the solvophobic force (analogous to the hydrophobic force in water) that drives surfactant self assembly, and how the surfactant micelle changes the IL nanostructure in the vicinity of the micelle. This study will use NIMROD to resolve these issues by provide unmatched detail regarding the interactions between surfactant micelles and ILs, and reveal how the presence of monomers and micelles influence IL nanostructure.
