Abstract

The conductivity (σ) measurement was carried out on water/dioctyl sulfosuccinate sodium salt (DOSS)/heptanol (decanol)/toluene reverse microemulsions. Addition of toluene was distinctly observed to inhibit the conductance percolation of water/DOSS/decanol/toluene systems. The effect of additives (sodium chloride, sodium salicylate and sodium cholate) with various concentrations on the conductivity behavior of water/DOSS/heptanol (decanol)/toluene systems was also investigated and discussed. The conductivity of a water/DOSS/heptanol/toluene system was almost unchanged in the concentration ranges of sodium chloride and sodium salicylate studied, while it decreased with the increase in the sodium cholate concentration. The conductance of the water/DOSS/decanol/toluene system increased with increasing of sodium cholate and sodium salicylate concentrations, and it changed little with the sodium chloride concentration. The lnσ value exhibited a linear correlation with temperature in the range of 5–40 °C. No percolation threshold induced by temperature was detected either in the absence or in the presence of additives. Furthermore, the activation energy for conductivity was estimated and discussed according to the Arrhenius type equation. The present study would provide useful information for selecting a suitable template for nanometer materials preparation.
