Summary

The microstructure of colloidal suspensions, both at rest and under flow, is a function of the particle and fluid properties, interparticle potential, and processing or flow history. Indeed, complex, nonlinear rheological phenomena, such as thixotropy and shear thickening, are associated with significant changes in microstructure during flow and processing. A modern understanding of colloidal suspension rheology thus necessitates measurement of colloidal suspension microstructure under flow as well as at rest. Two popular classes of experimental methods for microstructure measurement are introduced and explained, namely confocal microscopy and scattering of light, neutrons, and x-rays.
