Abstract

We have studied the isotropic cubic liquid crystalline phases formed by the surfactant didodecyl dimethyl ammonium bromide (DDAB) when mixed with water and octane, using the techniques of small-angle neutron scattering (SANS), freeze-fracture electron microscopy and rheology. Such liquid crystals are formed by the ordered arrangement of the aqueous and paraffinic microphases which are separated by a surfactant monolayer (or bilayer). Our results are consistent with a periodic constant mean curvature topology for these phases, which has the property of minimising the oil/water interfacial area for a given volume fraction.
