Electrical Conductivity in Oil Continuous Microemulsions

  • 330 Accesses

Abstract

The percolative conduction behaviour in water-in-oil microemulsion systems has been examined at different temperatures, hydration and frequencies. It has been found that the membrane rigidity of the surfactant monolayer of the microemulsion droplets caused by the solubilization of cholesterol plays an important role in electrical conduction. It has been concluded from the results that large interlinking clusters are formed at the percolation threshold point in which the charge carrier hops from one droplet to another and the whole system behaves like doped semiconductor when its frequency dependent electrical conductivity is considered.
