摘要：

The static dielectric constant and the conductivity versus temperature were studied on a water in oil microemulsion composed of perfluoropolyether (PFPE) oil and surfactant at a constant water to surfactant ratio for different oil to surfactant ratios. The evidence of a percolation phenomenon is shown. An analysis in terms of scaling laws and a calculation of the scaling exponents indicate a dynamic percolation process below the threshold for all of the samples studied and above the threshold, far from phase transition regions. The exponents of static percolation are found above the threshold, close to the phase transition.
