In spite of the apparent simplicity of silica’s composition and structure, scientists are still investigating fundamental questions regarding the formation, constitution, and behavior of colloidal silica systems. Colloidal Silica: Fundamentals and Applications introduces new information on colloid science related to silica chemistry as well as theoretical and experimental aspects of significant areas of colloidal silica science and technology. This resource is dedicated to helping researchers find new uses of silica and answers to practical problems as its industrial use continues to grow steadily in traditional and novel areas. Written by leading silica scientists around the world, this book reflects developments in the field since silica scientist Ralph K. Iler published his authoritative book on silica chemistry in 1979. It discusses properties and methods of characterization, synthesis, and preparation of silica in terms of industrial applications. Following an analysis of the surface chemistry of various silicas, the book explores methods for measuring particle size and useful characterization techniques for determining structure, stability, and reactivity. The authors then focus on various studies, analytical methods, and current applications involving silica gels and powders, silica coatings, colloidal silica, and sol-gel technology. Colloidal Silica: Fundamentals and Applications features up-to-date material relating to fields as diverse as catalysis, metallurgy, electronics, glass, ceramics, paper and pulp technology, optics, elastomers, food, health care, and industrial chromatography. It is ideal for scientists interested in silica chemistry and physics as well as those not familiar with the subject.

Silicone is an important class of materials used in applications that range from industrial assembly to everyday consumer products. Silicones are often delivered and synthesized in dispersion forms, the most common being liquid-in-liquid (emulsion), solid-in-liquid (suspension), air-in-liquid (foam) and solid-in air (powder). This book compiles a carefully selected number of topics that are essential to the understanding, creative design and production of silicone dispersions. As such, it provides the first unified description of silicone dispersions in the literature.

Until now colloid science books have either been theoretical, or focused on specific types of dispersion, or on specific applications. This then is the first book to provide an integrated introduction to the nature, formation and occurrence, stability, propagation, and uses of the most common types of colloidal dispersion in the process-related industries. The primary focus is on the applications of the principles, paying attention to practical processes and problems. This is done both as part of the treatment of the fundamentals, where appropriate, and also in the separate sections devoted to specific kinds of industries. Throughout, the treatment is integrated, with the principles of colloid and interface science common to each dispersion type presented for each major physical property class, followed by separate treatments of features unique to emulsions, foams, or suspensions. The first half of the book introduces the fundamental principles, introducing readers to suspension formation and stability, characterization, and flow properties, emphasizing practical aspects throughout. The following chapters discuss a wide range of industrial applications and examples, serving to emphasize the different methodologies that have been successfully applied. Overall, the book shows how to approach making emulsions, foams, and suspensions with different useful properties, how to propagate them, and how to prevent their formation or destabilize them if necessary. The author assumes no prior knowledge of colloid chemistry and, with its glossary of key terms, complete cross-referencing and indexing, this is a must-have for graduate and professional scientists and engineers who may encounter or use emulsions, foams, or suspensions, or combinations thereof, whether in process design, industrial production, or in related R&D fields.

Many industrial formulations such as detergents, paints, foodstuff and cosmetics contain both surfactants and polymers and their interaction govern many of the properties. This book is unique in that it discusses the solution chemistry of both surfactants and polymers and also the interactions between the two. The book, which is based on successful courses given by the authors since 1992, is a revised and extended version of the first edition that became a market success with six reprints since 1998. Surfactants and Polymers in Aqueous Solution is broad in scope, providing both theoretical insights and practical help for those active in the area. This book contains a thorough discussion of surfactant types and gives information of main routes of preparation. A chapter on novel surfactants has been included in the new edition. Physicochemical phenomena such as self-assembly in solution, adsorption, gel formation and foaming are discussed in detail. Particular attention is paid to the solution behaviour of surfactants and polymers containing polyoxyethylene chains. Surface active polymers are presented and their interaction with surfactants is a core topic of the book. Protein-surfactant interaction is also important and a new chapter deals with this issue. Microemulsions are treated in depth and several important application such as detergency and their use as media for chemical reactions are presented. Emulsions and the choice of emulsifier is discussed in some detail. The new edition also contains chapters on rheology and wetting. Surfactants and Polymers in Aqueous Solution is aimed at those dealing with surface chemistry research at universities and with surfactant formulation in industry.

The co-evolution of a strong theoretical framework alongside application of a range of sophisticated experimental tools engendered rapid advancement in the study of “giant micelles.” Beginning with Anacker and Debye’s 1951 experimental study of elongated micelles by light scattering and their subsequent theoretical inference that the thermodynamics of these structures would have to reflect an opposing force model, theory and experiment have progressed hand in hand. This progress, along with growing interest in the practical and industrial applications of these structures in cleansers, cosmetics, pharmaceuticals, and energy production, demands a comprehensive, single-source reference to the current state-of-the-science. Drawing on the expertise of internationally known scientists, Giant Micelles: Properties and Applications summarizes the range of behaviors encountered in solutions of micelles and their applications in industrial processes. The book introduces theoretical aspects of the rheological behavior and formation of giant micelles from different viewpoints including molecular-level thermodynamic theory and computer simulations. It continues by focusing on the results of a variety of experimental studies using methods such as cryo-transmission electron microscopy, scattering techniques, phase diagrams, linear and non-linear rheology, and chemical relaxation. Illustrating the properties of giant micelles on solid surfaces, the book also considers systems of smart micelles that respond to external stimuli by a change of shape. The authors describe giant micelles formed from amphiphilic block copolymers as well as non-covalent polymers that exhibit similar rheological behavior to giant micelles. Finally, the chapters address current and emerging applications of giant micelles in oil and gas production, drag reduction, drug-delivery formulations, and personal care products such as shampoo. By gathering a range of information into one volume, Giant Micelles: Properties and Applications provides scientists with an essential reference on these fascinating materials and their emerging role in industrial application.
