摘要：

We study static electrical conductivity of water-in-oil microemulsions in the single-phase region. Below the percolation threshold, the data can be interpreted in terms of a fluctuating-charge model. Above the percolation threshold, in the lamellar region, the conductivity is consistent with randomly oriented water layers separated by surfactant sheets. The loci of the percolation thresholds are measured for different values of water to surfactant molar ratio and explained in terms of a continuum percolation model.
