Title

Developing µRheoSANS for ultra-hig shear rate rheometry and SANS of fluids

Abstract

RheoSANS contributes significantly to our growing understanding of the response of complex fluids and soft matter to stress and strain. However, industrial processes often shear fluid at rates that are up to two orders of magnitude greater than current capabilities. To achieve the higher shear rates, we propose a new method µRheoSANS combining pressure-driven slit rheometry and SANS. We request experiment time on D22 to probe two objectives: 1. to illustrate and evaluate the new method, and 2. to investigate new physics at the higher shear rate. In particular, we will test the breakup of wormlike micelles at high stress.
