percolative conduction arises due to the hopping of the charge carriers across the
surfactant monolayer of the droplets, and the aggregates open up only at the onset of
formation of bicontinuous microemulsions. … In this paper we have tried toresolve the
controversy by studying the electrical conductivity and water self-diffusion coefficients of the
microemulsion medium in the percolative conduction region as well as at the onset of
bicontinuous structure formation. … Conclusions It can, therefore, be conclusively statedthat …
The electrical conductivityof the disordered systems is often interpreted by using the concept of percolation transition which signifies the existence of the conducting species in a conductor-insulator composite material. 1 Measurements of the conductivity
