In-situ structuring rheometer based on chaotic advection

摘要

An in-situ structuring rheometer provides a means to develop and measure the rheological properties of structured materials such as those having various polymer blend morphologies or particle networks. Chaotic advection of liquid contained within a cavity is instilled by controlled motions of boundary surfaces and, concomitantly, forces and displacements on the boundary surfaces are measured, indicating at least one of a flow- or a structure-related property.
