The process of water-induced electrical percolation of the anionic surfactant sodium bis(2-ethylhexyl)sulfosuccinate (AOT) in reverse microemulsions has been studied. The effect of addition of nonionic polymeric surfactants Pluronic F127 and Tyloxapol on the electrical percolation threshold of AOT reverse microemulsions has been studied. An increase in Pluronic additive concentration was found to inhibit percolation both up to the critical micelle formation concentration and in the range beyond the critical micelle formation concentration. It is established that under conditions of equal concentration, the electrical percolation threshold in the case of Pluronic-F127 additive is reached at a higher value of W (W=44) than in the case of tyloxapol additive (W=32).
