A dispersion is a system of unmixable phases in which one phase is continuous and at least one is finely distributed. Examples are found in many industrial applications, including emulsions, suspensions, foams, and geld. The control of their flow characteristics - rheology - is essential in their preparation, long-term physical stability and application. Filling the need for a practical, up-to-date book connecting the stability/instability of the dispersion to its rheological behavior, this title aids in understanding the principles of rheology and the techniques that can be applied. From the contents: * General Introduction * Interparticle Interactions and Their Combination * Principles of Viscoelastic Behavior * Rheology of Suspensions * Rheology of Emulsions * Rheology of Modifiers, Thickeners, and Gels * Use of Rheological Measurements for Assessment and Prediction of the Long-Term Physical Stability of Formulations (Creaming and Sedimentation)

Rheology: Theory and Applications, Volume 5 focuses on overtly fluid behavior of polymers, including the theory of large deformations, thermoelastic effects, elastic phenomena observed during the extrusion of polymeric melts, and theories of the structure of liquids and glasses. The selection first elaborates on the application of large deformation theory to the thermomechanical behavior of rubberlike polymers and unstable flow of molten polymers. Discussions focus on the mechanism proposed for unstable flow, ripple and associated effects, direct observation of waviness phenomena, empirical behavior of porous, unfilled, and filled rubberlike polymers, and problems connected with the interpretation of mechanical response parameters. The text then examines elasticity effects in polymer extrusion and strength and extensibility of elastomers. The publication takes a look at free volume and polymer rheology and studies of the deformation of crystalline polymers. Topics include the contribution of the two orientation processes to the birefringence, deformation of superstructure, rate of orientation of crystalline regions, free volume and physical state, glass transition and free volume, and reappraisal of time-temperature superposition. The manuscript also elaborates on the deformation and dissipative processes in high polymeric solids and the thermodynamics of deformation. The selection is a vital source of data for researchers interested in the theories and applications of rheology.

Dispersionen sind ein heterogenes Gemisch aus zwei Stoffen, die sich nicht miteinander mischen. In der vorliegenden Arbeit werden sowohl Suspensionen bestehend aus einer festen dispersen Phase in einem flussigen Dispersionsmedium, Emulsionen bestehen aus zwei nicht mischbaren Flussigkeiten als auch Schaume, gebildet aus einer Gasphase dispergiert in einer Flussigkeit, untersucht. Als Hauptcharakterisierungsmethode dient die Fourier Transformations-Rheologie (FT-Rheologie), welches eine mechanische Charakterisierungsmethode im nichtlinearen Bereich darstellt.

One of the few textbooks in the field, this volume deals with several aspects of the dynamics of colloids. A self-contained treatise, it fills the gap between research literature and existing books for graduate students and researchers. For readers with a background in chemistry, the first chapter contains a section on frequently used mathematical techniques, as well as statistical mechanics. Some of the topics covered include: • diffusion of free particles on the basis of the Langevin equation •the separation of time, length and angular scales; • the fundamental Fokker-Planck and Smoluchowski equations derived for interacting particles • friction of spheres and rods, and hydrodynamic interaction of spheres (including three body interactions) • diffusion, sedimentation, critical phenomena and phase separation kinetics • experimental light scattering results. For universities and research departments in industry this textbook makes vital reading.

This book covers the physical side of colloidal science from the individual forces acting between particles smaller than a micrometer that are suspended in a liquid, through the resulting equilibrium and dynamic properties. A variety of internal forces both attractive and repulsive act in conjunction with Brownian motion and the balance between them all decides the phase behaviour. On top of this various external fields, such as gravity or electromagnetic fields, diffusion and non-Newtonian rheology produce complex effects, each of which is of important scientific and technological interest. The authors aim to impart a sound, quantitative understanding based on fundamental theory and experiments with well-characterised model systems. This broad grasp of the fundamentals lends insight and helps to develop the intuitive sense needed to isolate essential features of the technological problems and design critical experiments. The main prerequisites for understanding the book are basic fluid mechanics, statistical mechanics and electromagnetism, though self contained reviews of each subject are provided at appropriate points. Some facility with differential equations is also necessary. Exercises are included at the end of each chapter, making the work suitable as a textbook for graduate courses in chemical engineering or applied mathematics. It will also be useful as a reference for individuals in academia or industry undertaking research in colloid science.
