Abstract

Dynamic light scattering (DLS) is an experimental method to access static or dynamic physical parameters of suspensions colloidal systems relevant to micron scales. This technique has the advantage of being non-invasive. An experimental setup was developed to study flow constraints through light scattering of concentrated colloidal suspensions under shear stress-related flows. The combination of rheological measurements and light scattering, gives results that provide a better understanding of the phenomena present in the shaping.
