(a) X-ray reflectivity of water (circles) and aqueous [C12mim]Cl solution (triangles). The solid curve for water is the theoretical prediction calculated using equations (2)–(4) with RF denoted by the dashed curve. The data for the aqueous [C12mim]Cl solution were fitted using a two-box model based on the dodecyl chain layer and the Cl− anion layer. (b) Electron density profiles corresponding to the data fits. The inset shows a schematic of the [C12mim]Cl monolayer arrangement. |
