Planar and curved electrolytic liquid-liquid interfaces — •Markus Bier — MPI f. Metallforschung, Heisenbergstr. 3, 70569 Stuttgart

The interfacial tension of a liquid-liquid interface in the presence of microscopic ions is studied for the cases of planar as well as curved interfaces. Unequal partitioning of the ions between the two liquid phases is identified as the mechanism dominating the planar interfacial tension at low ionic strengths. Several scaling regimes of the curved interfacial tension are found which allows, e.g., to assess the range of validity of low-curvature expansions.
