Left -- Predicted radii of microemulsion droplets as a
function of the volume ratios of alcohol to surfactant in microemulsions. The
predictions are for a system consisting of the surfactant SDS, 1-pentanol,
0.3 M NaCl, water, and cyclohexane. The total
volume fraction of the surfactant in the microemulsions is 0.01. Filled
circles denote O/W droplets, and open circles correspond to W/O droplets. Right -- Oil-water interfacial tensions at the flat
surfaces between microemulsion phases and excess dispersed phases as a
function of the volume ratios of alcohol to surfactant in microemulsions. All
the system characteristics are identical to those described for the left
figure. Filled symbols are for O/W microemulsions, and open symbols refer to
W/O microemulsions. |
