Lecture Abstract

=========================================================================

Rheology by definition is the study of the deformation and flow behavior
of materials, or "the science of flow".  Flow behavior, often complex, is
important in many industrial processes and can determine the success or
failure of a wide range of commercial products.  Paints and industrial
coatings, molded plastics, adhesives, personal care products and cosmetics,
inks, cement, drilling muds, ceramic slips, solder pastes, foodstuffs and
medicines are examples of the range of industrial materials whose commercial
viability depends on having the “right” rheology.  These materials may be
called “complex fluids”, for which the viscosity and elasticity are not
material constants but rather are complex functions of stress, strain,
and strain history.  For such materials, the necessary rheological
properties must be defined with due regard to the flow or stress conditions
which prevail during processing and application.  However, it is often
difficult to link fundamental properties with real-world performance.  
This lecture surveys the subject of dispersion rheology, from fundamentals
to its application to the understanding of performance problems of
complex fluids, especially coatings.  Detailed attention will be given to
the measurement and interpretation of the “flow curve” for fluid
dispersions.
