Rheology and nuclear magnetic resonance measurements under shear of sodium dodecyl sulfate/decanol/water nematics

Abstract

This paper reported on the rheology of nematic lyotropic system sodium dodecyl sulfate, decanol and water (SDS-Dec). The flow behavior of the N C and N D phases in terms of the transient shear stress were studied by using different rheological histories. The rheological experiments and 2 H nuclear magnetic resonance (NMR) investigations showed that the SDS-Dec nematics, either calamitic or discotic, are textured nematics of the flow-alignment type.
