Water-AOT-alkylbenzene microemulsions: Influence of alkyl chain length on structure and percolation behavior

► AOT-based water-in-oil droplet microemulsions with different alkylbenzenes as oil phase. ► Percolation behavior studied by conductivity measurements, structure studied by SAXS. ► Droplet radius increases linearly with molar water to surfactant ratio. ► Percolation can be induced by increasing alkyl chain length.
