Filling the gap for a reference dedicated to the characterization of polymer blends and their micro and nano morphologies, this book provides comprehensive, systematic coverage in a one-stop, two-volume resource for all those working in the field. Leading researchers from industry and academia, as well as from government and private research institutions around the world summarize recent technical advances in chapters devoted to their individual contributions. In so doing, they examine a wide range of modern characterization techniques, from microscopy and spectroscopy to diffraction, thermal analysis, rheology, mechanical measurements and chromatography. These methods are compared with each other to assist in determining the best solution for both fundamental and applied problems, paying attention to the characterization of nanoscale miscibility and interfaces, both in blends involving copolymers and in immiscible blends. The thermodynamics, miscibility, phase separation, morphology and interfaces in polymer blends are also discussed in light of new insights involving the nanoscopic scale. Finally, the authors detail the processing-morphology-property relationships of polymer blends, as well as the influence of processing on the generation of micro and nano morphologies, and the dependence of these morphologies on the properties of blends. Hot topics such as compatibilization through nanoparticles, miscibility of new biopolymers and nanoscale investigations of interfaces in blends are also addressed. With its application-oriented approach, handpicked selection of topics and expert contributors, this is an outstanding survey for anyone involved in the field of polymer blends for advanced technologies.

This book aims to introduce the reader to a wide range of polymer characterization techniques including thermal, rheology, mechanical, relaxational, scattering, and spectroscopic analysis. In addition to discussing the techniques and their experimental considerations in general, the chapters will show how the techniques are applied to polymer systems and how the data obtained is analyzed and interpreted. In order to connect each technique to applications, each chapter explains the use of the technique in the popular application of polymer blends. The blending of polymers continues to be a major area of polymer research in academia and industry, and in addition to its instructive role, each chapter serves as a review of the blend literature as relevant to a polymer blends researcher.

Die enormen Zuwachsraten in der Kunststofferzeugung und -anwendung erhöhen die Forderung nach aussagekräftigen Mess- und Auswerteverfahren in der Kunststoffprüfung. Durch die Fortschritte in der elektronischen Messtechnik haben sich sowohl die klassischen Prüfverfahren weiterentwickelt als auch völlig neuartige Methoden etabliert. Die Aussagekraft dieser Kenngrößen zur Quantifizierung der Zusammenhänge zwischen der Mikrostruktur und den makroskopischen Eigenschaften wird dargestellt. Zusätzliche Informationen über die ablaufenden Schädigungsprozesse und -mechanismen können durch die Anwendung gekoppelter zerstörungsfreier Kunststoffprüfverfahren bzw. hybrider Methoden der Kunststoffdiagnostik gewonnen werden. An Hand von Beispielen zur Optimierung von Kunststoffen und Verbunden sowie zur Bewertung von Bauteileigenschaften wird ein werkstoffwissenschaftlich begründeter Einblick in die moderne Kunststoffprüfung vermittelt.

Lignocellulosic materials are a natural, abundant and renewable resource essential to the functioning of industrial societies and critical to the development of a sustainable global economy. As wood and paper products, they have played an important role in the evolution of civilization. Improvement of the quality and manufacturing efficiency of such products has often been hampered by the lack of understanding of the complex structures and chemical compositions of the materials. Due to increasing economic and environmental issues concerning the use of petrochemicals, lignocellulosic materials will be relied upon as feedstock for the production of chemicals, fuels and biocompatible materials. Significant progress has been made to use lignocellulosic materials for the production of fuel ethanol and as a reinforcing component in polymer composites. Effective and economical methods for such uses, however, remain underdeveloped, partly due to the difficulties encountered in the characterization of the structures of native lignocelluloses and lignocelluloses-based materials. Improved methods for the characterization of lignocellulosic materials are needed. Characterization of Lignocellulosic Materials covers recent advances in the characterization of wood, pulp fibres and papers. It also describes the analyses of native and modified lignocellulosic fibres and materials using a range of advanced techniques such as time-of-flight secondary ion mass spectrometry, 2D heteronuclear single quantum correlation NMR, and Raman microscopy. The book provides a survey of state-of-the-art characterization methods for lignocellulosic materials, for both academic and industrial researchers who work in the fields of wood and paper, lignocelluloses-based composites and polymer blends, and bio-based fuels and materials.

Modern materials include a vast array of polymers and plastics which are found in applications such as housing, appliances, clothing and household textiles and automotive and aerospace industries. Thus research scientists, engineers and materials science graduate students need to be aware of the methods and techniques required to understand the structure-property relations of polymer materials. This book will review the field of the microscopy of polymers. There is a vast literature which describes the research results obtained by study of polymer materials using microscopy and other complementary analytical techniques and such studies are best left to journals on specific topics. The major objective of this text is to provide the basic microscopy techniques and specimen preparation methods applicable to polymers. The book will attempt to provide enough detail so that the methods described can be applied, and also to reference appropriate publications for the investigator interested in more detail. The selection of two authors for this text came from the desire for a comprehen sive review of polymer microscopy with emphasis on methods and techniques, rather than on research results. The synergism provided by two authors with widely varied backgrounds was thought to be important: one author (LCS) has an industrial focus and a background in chemistry whilst the other (DTG) has an academic environment and offers a background in polymer physics.

"Thermal Analysis of Polymeric Materials" systematically treats macroscopic measurements by thermal analysis and the quantitative link to microscopic, molecular structure and mobility. Reversible and irreversible thermodynamics, kinetics, quantum mechanics, and statistical thermodynamics are the roots of the described thermal analysis. The book aims to broaden readers’ understanding of materials and the connection of flexible macromolecules (polymers) to small molecules and rigid macromolecules (minerals, salts, and metals). An effort is made to discover how the long, flexible molecules fit into their small phases which are characterized as microphases or nanophases. Their order ranges from amorphous to mesophase-like and crystalline. Ultimately, it is shown that the basic structure-property-processing triangle is connected to the better-known types of molecules and their common macroscopic phases.
