ELECTRICAL CONDUCTIVITIES OF 3-PHASE EMULSIONS .1. STRONGLY WETTING MIDDLE PHASE

Electrical conductivities of steady-state, three-phase (macro)emulsion s formed by the top (T), middle (M), and bottom (B) phases of the amph iphile/oil/''water'' (i.e., aqueous 10 mM NaCl) system C4H9OC2H40H/n-d ecane/water have been measured and compared with the predictions of eq uations from the literature or that we have proposed. In all cases the continuous phase could be deduced from the combination of experiment and theory, but less information was obtained about dispersed-phase st ructures. Three new conductivity equations and two new three-phase dis persion morphologies have been proposed.
