Gk. Johnson et al., ELECTRICAL CONDUCTIVITIES OF 3-PHASE EMULSIONS .2. C6H13(OC2H4)2OH N-TETRADECANE WATER WITH WETTING AND NONWETTING MIDDLE PHASES, Langmuir, 10(8), 1994, pp. 2523-2527
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.
