Probing shear-banding in suspensions of soft sphere using RheoSANS own the flow direction
Shear-banding is an ubiquitous phenomenon for soft materials under flow in which it is observed a transient or steady-state non-homogeneous flow with formation of bands sliding with different velocity. It has been reported for a variety of colloidal suspensions, from hard sphere colloids to ultrasoft star polymers. Our data shows indication of shear banding also in suspensions of microgels. Despite shear banding is a well known phenomenon, the link between shear banding and the evolution of the microstructure and dynamics of colloidal suspensions under flow has been scarcely explored in experiments. Here we propose to study the shear banding observed in microgel suspension in the flow-direction using the 1,2, shear cell available on D22. The possibility of performing spatial resolved measurements in the direction of the flow will provide unique new insight on this phenomenon which can clarify its microscopic origin.
