Abstract
Electrical conductivities of steady-state, three-phase (macro)emulsion s formed by the top (T), middle (i.e, microemulsion, M), and bottom (B ) phases of the amphiphile/oil/''water'' (i.e., aqueous 10 mM NaCl) sy stem C6H13(OC2H4)2OH/n-tetradecane/water have been measured and compar ed with conductivities predicted by equations for different emulsion m orphologies. Two temperatures were used, one above and one below the t emperature of the middle-phase wetting transition. The appropriate con ductivity equations, and thus the emulsion morphologies, appeared to d epend on the wettability of the T-B interface by the middle phase.
