Polymer nanocomposites have revolutionised material performance, most notably in the plastics, automotive and aerospace industries. However, in order to be commercially viable, many of these materials must withstand high temperatures. In this book, leaders in the field outline the mechanisms behind the generation of suitable polymer systems, pulling together recent research to provide a unified and up-to-date assessment of recent technological advancements. The text is divided into two clear sections, introducing the reader to the two most important requirements for this material type: thermal stability and flame retardancy. Special attention is paid to practical examples, walking the reader through the numerous commercial applications of thermally stable and flame retardant nanocomposites. With a strong focus on placing theory within commercial context, this unique volume will appeal to practitioners as well as researchers.

When many polymers are heated they transform directly into carbons, without passing through an intermediate liquid paste. Such carbons are termed polymetric carbons. Phenolic resins yield an isotropic impervious black glassy carbon which is hard enough to scratch window glass and has interesting electronic properties. polyacrylonitrile fibres yield carbon fibre with enormous stiffness and strength. Combinations of the two produce the strongest carbon material (carbon-fibre-reinforced carbon). Carbon-fibre-reinforced plastics are revolutionary low density-high-stiffness materials. This 1976 book brings together data from the authors' work to describe the manufacture of polymetric carbons. It provides a description of physical, mechanical and chemical properties which are related as closely as possible to the revealed structure. Emphasis is placed on the more interesting aspects, such as development of high-strength, high-stiffness material, the semi-conducting behaviour of intermediate materials and the absorption of gases in the more open structure of absorbent chracoals.

This book was first published in 2007. Polymers exhibit a range of physical characteristics, from rubber-like elasticity to the glassy state. These particular properties are controlled at the molecular level by the mobility of the structural constituents. Remarkable changes in mobility can be witnessed with temperature, over narrow, well defined regions, termed relaxation processes. This is an important, unique phenomenon controlling polymer transition behaviour and is described here at an introductory level. The important types of relaxation processes from amorphous to crystalline polymers and polymeric miscible blends are covered, in conjunction with the broad spectrum of experimental methods used to study them in 2007. In-depth discussion of molecular level interpretation, including atomistic level computer simulations and applications to molecular mechanism elucidation, are discussed. The result is a self-contained approach to polymeric interpretation suitable for researchers in materials science, physics and chemistry interested in the relaxation processes of polymeric systems.

Understanding the dynamics of reactive polymer processes allows scientists to create new, high value, high performance polymers. Chemorheology of Polymers provides an indispensable resource for researchers and practitioners working in this area, describing theoretical and industrial approaches to characterising the flow and gelation of reactive polymers. Beginning with an in-depth treatment of the chemistry and physics of thermoplastics, thermoset and reactive polymers, the core of the book focuses on fundamental characterization of reactive polymers, rheological (flow characterization) techniques and the kinetic and chemorheological models of these systems. Uniquely, the coverage extends to a complete review of the practical industrial processes used for these polymers and an insight into the current chemorheological models and tools used to describe and control each process. This book will appeal to polymer scientists working on reactive polymers within materials science, chemistry and chemical engineering departments as well as polymer process engineers in industry.

Three-dimensional molded interconnect devices (MIDs) enable mechanical, electronic, optical, thermal and fluidic functions to be integrated into injection-molded components. Function integration on this scale goes hand in hand with a high level of geometrical design freedom and opportunities for miniaturization, plus the associated reduction in weight and savings on product costs. MIDs are made primarily of recyclable thermoplastics, so they are more environmentally compatible than alternatives produced using other available technologies. MIDs are used in virtually every sector of electronics. The many standard applications for MIDs in the automotive industry in particular also drive for further development and research into MID technology. The significance of MID technology is also increasing in medical engineering, IT and telecommunications and in industrial automation, with numerous applications now successfully implemented in all these various fields. This book offers a comprehensive insight into the state of the art in 3D-MID technology along the entire process chain. Individual chapters, moreover, deal with systematics of targeted development of MID parts and explore, with a dozen and more successful series-production applications as examples, the widely diverse fields of application for MID technology.

This long awaited and thoroughly updated version of the classic text (Plenum Press, 1970) explains the subject of electrochemistry in clear, straightforward language for undergraduates and mature scientists who want to understand solutions. Like its predecessor, the new text presents the electrochemistry of solutions at the molecular level. The Second Edition takes full advantage of the advances in microscopy, computing power, and industrial applications in the quarter century since the publication of the First Edition. Such new techniques include scanning-tunneling microscopy, which enables us to see atoms on electrodes; and new computers capable of molecular dynamics calculations that are used in arriving at experimental values. Chapter 10 starts with a detailed description of what happens when light strikes semi-conductor electrodes and splits water, thus providing in hydrogen a clean fuel. There have of course been revolutionary advances here since the First Edition was written. The book also discusses electrochemical methods that may provide the most economical path to many new syntheses - for example, the synthesis of the textile, nylon. The broad area of the breakdown of material in moist air, and its electrochemistry is taken up in the substantial Chapter 12. Another exciting topic covered is the evolution of energy conversion and storage which lie at the cutting edge of clean automobile development. Chapter 14 presents from a fresh perspective a discussion of electrochemical mechanisms in Biology, and Chapter 15 shows how new electrochemical approaches may potentially alleviate many environmental problems.

Rubber elasticity is an important sub-field of polymer science. This book is in many ways a sequel to the authors' previous, more introductory book, Rubberlike Elasticity: A Molecular Primer (Wiley-Interscience, 1988), and will in some respects replace the now classic book by L.R.G. Treloar, The Physics of Rubber Elasticity (Oxford, 1975). The present book has much in common with its predecessor, in particular its strong emphasis on molecular concepts and theories. Similarly, only equilibrium properties are covered in any detail. Though this book treats much of the same subject matter, it is a more comprehensive, more up-to-date, and somewhat more sophisticated treatment.

It is difficult to imagine how our highly evolved technological society would function, or how life would even exist on our planet, if polymers did not exist.

It has been well-recognized that polymer blends offer a key option in solving emerging application requirements. The ability to combine existing polymers into new compositions with commercializable properties offers the advantage of reduced research and development expense compared to the development of new monomers and polymers to yield a similar property profile. An additional advantage is the much lower capital expense involved with scale-up and commercialization. Another specific advantage of polymer blends versus new monomer/polymer compositions is that blends often offer property profile combinations not easily obtained with new polymeric structures. In the rapidly emerging technology landscape, polymer blend technology can quickly respond to developing needs. This book offers a comprehensive overview of this important field, in particular a unique and extensive literature research on all aspects of this technology. It can be utilized as a reference text as well as a textbook for a graduate level course on polymer blends.
