Abstract

The addition of a second surfactant to an otherwise thermodynamically stable microemulsion causes interfacial and bulk effects: the combination of AOT and C12E5 supports the formation of planar interfaces (considering the molecular geometries of the surfactants) which induces a sphere to oblate ellipsoid (≈ disk) transition ensuing a lamellar liquid crystalline phase. Heats of adsorption of C12E5 (adsorbed on an H2O/AOT/i-C8H18 interface) corroborate the existence of two different interfacial states. The phase transition was inferred from combining conductometric and electro-optic Kerr effect studies.
