摘要：

The static properties of lyotropic lamellar phases have been investigated for a long time. Recently, we studied the dynamic properties and more specifically the effect of shear on these phases. Using different techniques (conoscopy, light, neutron and X-ray scattering, microscopy and rheology), the different stationary orientation states of a lamellar phase (in a quaternary mixture water-SDS-pentanol-dodecane) have been analyzed ; in this paper we describe the analysis of the oriented state of these lamellar phase at high shear rates; we consider a Gaussian distribution to define the mosaicity of this orientation where the normal of the membrane is parallel to the velocity gradient.
