Abstract
Rheology is the study of the flow and deformation of matter. This interdisciplinary field encompasses many different types of materials and applications, both in academia and industry. One of the most challenging and practical areas in which technical strides have been made is dispersion chemistry. Rheology can be used to characterize not only flow properties of a material, but also structural features.
This introduction is intended to help newcomers to the field to comprehend, relatively quickly, the practical nature of rheological information and to recognize the impact of the type of internal structure on rheological properties. This article describes dispersions well-suited to rheological study and the types of interparticle forces responsible for their internal structure. The fundamental terms and concepts of rheology are explained using practical examples to illustrate how rheological techniques distinguish dispersions in terms of both flow properties and structural features.

Manuel Dolz , Jesús Delegido , Alejandro Casanovas and María-Jesús HernándezJournal of Chemical Education2005 82 (3), 445An experiment to study the flow of Newtonian and non-Newtonian fluids is proposed. The method is based on measurement of the drag force on a sphere immersed in a moving fluid. The sphere–fluid relative velocity can be changed to obtain the dependence of ...
