Polymers in Particulate Systems: Properties and Applications
Vincent A. Hackley, P Somasundaran, J A. Lewis
Soluble polymers are key additives for a broad range of industrial and biomedical applications, including advanced ceramics, mineral separations, high performance cement, and bioceramic coatings and composites. Such species find widespread use as dispersant, superplasticizers, flocculants, thickeners, binders, crystal growth inhibitors, and bonding agents. Furthermore, natural polymers play a crucial role in biomineralization mechanisms for the formation of bone and teeth. Developing a fundamental understanding of how these macromolecular species bond to surfaces and influence colloidal stability, flow and structure of complex particulate suspensions, and the consolidation behavior and mechanical properties of as-formed green bodies (or films) is therefore crucial to advancing a number of technologies. The aim of this book is to provide researchers and engineers with the necessary information to effectively design new particulate formulations and processing routes incorporating polymeric additives, and to help them to better understand and control the systems with which they are currently working. To accomplish this goal we have taken a balanced, multidisciplinary approach, enlisting technical experts from diverse fields to address a variety of key issues in a broad range of material applications. We believe the reader will find this to be an invaluable and unique resource, as it combines both fundamental and applied aspects. For convenience, the chapters are organized into three parts. Part 1 focuses on fundamental principles related to colloidal stability and polymer functionality. Part II focuses on the rheology of concentrated suspensions, and Part III addresses processing and biomedical applications. The contributors were selected from a group of internationally recognized researchers, many of whom presented their work at the Symposium on Polymers in Particulate Systems held at the annual meeting of the American Ceramic Society in St. Louis. Additional contributions were solicited in order to achieve a more comprehensive technical landscape.
