Abstract
The dependence of transport characteristics (kinematic viscosity, conductivity, diffusion coefficient) of microemulsions in the octane/water/pentanol/sodium dodecyl sulfate system on the volume fraction of water (Φ) was studied by viscosimetry, conductometry, and photon correlation spectroscopy The percolation character of the specific conductivity of microemulsions is revealed; the conductivity and geometrical percolation thresholds are determined. The known percolation models of microemulsions and the dependence of the specific conductivity on the most probable dimension of microdrops are discussed. A cellular model of the microemulsion studied is proposed and its validity is shown in the region of comparatively low Φ values above the conductivity percolation threshold.
