Precise determination of concentration gradient in shear banding wormlike micelle solutions
The search for the physical origin of shear banding has motivated many theoretical and experimental studies and yet no consensus has emerged. Thanks to the 1-2 shear cell and its spatially-resolved measurements taken along the velocity-gradient direction, it is now possible to elucidate the shear banding behavior of WLM solutions quite precisely. A combination of measurements of sample transmission, coherent scattering and incoherent scattering will be used to determine whether concentration gradients are present in a couple of shear banding WLM solution while simultaneously decreasing the associated uncertainties of the measurements and shedding light to the basis of this phenomenon.
