ELECTRICAL-CONDUCTIVITY AND PERCOLATION IN WATER-IN-OIL MICROEMULSIONS

Electrical conductivity has been used to characterize disperse systems for a long time, but it is only recently that a more systematic exper imental and theoretical work has been undertaken. This review is an at tempt to show that the understanding of electrical conductivity in mic roemulsions is not only important from a practical point of view but a lso can be stimulating for experimental and theoretical basic research . We focus on water-in-oil (W/O) microemulsions and on electrical cond uctivity in relation to the percolation.
