Recently microemulsions are used as nanotemplet to designinorganic nanostructure materials. The physical parameters in SDS/(Hexylamine+Heptane)/watermicroemulsion system, were analyzed by the percolation and effective medium theories. The conductivitybehavior and parameters of water droplets can be described. The initial solutions, consistsof different proportion of heptane to hexylamine concentrations such as (missing). But the (missing)ratio in each initial solution is kept equal to (15:85)]. The addition of water concentrationto each initial solution at beginning tends to formation of reverse micelle water droplet structure.In this paper, the electrical conductivity, radius of droplets and average number of droplets werecalculated. The calculation carried out with increasing water concentration in each mother solution.The results indicated that: 1. The average number of droplets reduces with increasingwater concentration. 2. The radius of droplets extended with addition of water concentration. Theabove two arguments tends to enlargment and recombination of water droplets. 3. The electricalconductivity values in initial stage increases with addition of water content, then it turns to flatenature. This change in behavior as a function of water concentration is corresponding to structuraltransformation from oil continuous water droplet to bicontinuous structure.30
