Liquid crystal displays were discovered in the 1960s, and today we continue to enjoy the benefits of that fundamental discovery and its translation into a wide variety of products. Like liquid crystals, polymers are unusual materials, and have similarly enjoyed a great deal of research attention because of their vast applications and uses and complex fundamental properties. The combination of liquid crystal and polymer properties produces a broad array of new effects-spanning from densely crosslinked, rigid polymer networks to weakly crosslinked elastomers-that are not simply manifestations of either native liquid crystals or polymers alone. Cross-Linked Liquid Crystalline Systems brings together liquid crystal and polymer systems and their variations. The field, much like traditional liquid crystals, is one of an interdisciplinary nature with a broad spectrum, from the very fundamental questions of nature to a myriad of practical uses. There seems to be no shortage of unusual properties and far-reaching applications in densely crossed-linked liquid crystal systems and liquid crystal elastomers. These systems provide a rich new avenue for both fundamental and applied research and continue to fascinate scientists and engineers. Specifically, this book covers: Cross-linked networks created from reactive mesogen materials Manipulation of liquid crystalline by external constraints Advances in liquid crystal display screen technology Physical and electromagnetic properties of elastomers and magnetic gels Computer simulations and theory of liquid crystal polymeric networks and elastomers Side-on nematic liquid-crystalline elastomers for artificial muscle applications Liquid crystal display technology has driven much of the fundamental research in crosslinked liquid crystalline systems. The systems' ability to enforce three-di

This book creates a new perspective on the design of plastic parts. In many books there is a strong focus on the material, the material properties, and the calculation or dimensioning. What is often not taken into account is that very many plastic components only have to withstand low loads; in very many applications, the focus is on the actual design. This requires a good understanding of the injection molds that must be built to produce the plastic components. Depending on the design of the injection molded component, these molds become more complex and more prone to failure during production. The complex process of manufacturing a plastic part becomes holistically understandable as a link is created between the molder, the mold maker, and the part designer. The focus is on injection molds and therefore on thermoplastics. Everything that is necessary for the design and manufacture of an injection molded component is presented in a simple, extremely practical manner and limited to the essentials. Many descriptive pictures as well as examples based on the demonstration component ""Polyman"" facilitate the understanding enormously.

In the last 10 years there have been major advances in fundamental understanding and applications and a vast portfolio of new polymer structures with unique and tailored properties was developed. Work moved from a chemical repeat unit structure to one more based on structural control, new polymerization methodologies, properties, processing, and applications. The 4th Edition takes this into account and will be completely rewritten and reorganized, focusing on spin coating, spray coating, blade/slot die coating, layer-by-layer assembly, and fiber spinning methods; property characterizations of redox, interfacial, electrical, and optical phenomena; and commercial applications.

Discovered in the twentieth century, carbon nanotubes (CNT) were an integral part of science and industry by the beginning of the twenty first century, revolutionizing chemistry, physics, and materials science. More recent advances in carbon nanotube production methods have resulted in a tremendous push to incorporate CNTs into polymer matrices. Although many advances have been made, two major obstacles continue unresolved: the enhancement of interfacial adhesion between CNTs and polymer matrix, and the improvement of dispersion of CNTs in polymers. Both substantial original contributors to the field, the authors present Carbon Nanotubes for Polymer Reinforcement, the first monograph on various conventional and innovative techniques to disperse and functionalize carbon nanotubes for polymer reinforcement, elegantly explaining the basic sciences and technologies involved in those processes. Topics covered include: * Use of CNTs in fabricating novel polymer composites * Principles and mechanisms behind CNT dispersion and functionalization * Methods for the functionalization and dispersion of CNTs in polymer matrices * Effects of CNTs on functional and mechanical properties of polymer composites * Optimization of CNT/polymer nanocomposite fabrication Carbon Nanotubes for Polymer Reinforcement is a comprehensive treatment and critical review of the new class of polymer nanocomposites, and points to areas of future developments. Composites engineers, scientists, researchers, and students will find the basic knowledge and technical results contained herein informative and useful references for their work, whether for advanced research or for design and manufacture of such composites.

Polymer-based smart materials have become attractive in recent years due to the fact that polymers are flexible and provide many advantages compared to inorganic smart materials: they are low cost, they are easy to process, and they exhibit good performance at nano- and microscale levels. This volume focuses on a different class of polymers that are used as smart materials in the areas of biotechnology, medicine, and engineering. The volume aims to answer these questions: How do we distinguish 'smart materials'? and How do they work? The chapters lay the groundwork for assimilation and exploitation of this technological advancement. Four of the key aspects of the approach that the authors have developed throughout this book are highlighted, namely the multidisciplinary exchange of knowledge, exploration of the relationships between multiple scales and their different behaviors, understanding that material properties are dictated at the smallest scale, and, therefore, the recognition that macroscale behavior can be controlled by nanoscale design.

Leading researchers from industry, academia, government, and private research institutions across the globe have contributed to this volume, covering new research on nanocomposites, polymer technology, and electrochemistry.

Plastic has become a ubiquitous part of modern life. A cheap, lightweight material, it is used in everything from food packaging to consumer electronics and microbeads in cosmetic products. However, we are becoming increasingly aware of the problems our reliance on plastic is causing in the environment. For example, recent campaigns have highlighted the build-up of microbeads in the marine environment and the damage this is doing to wildlife, and the problem of marine litter, often in very remote locations. There are also concerns over exposure to plasticisers and their possible consequences for health. The plastics industry is under increasing pressure, not only from the government and environmental groups, but also from consumers, to improve the environmental impact of their products. This book presents an introduction to the uses of plastics and an overview of how they interact with the environment. It is a valuable resource for students studying environmental science as well as researchers working in the plastics industry, and policy makers and regulators concerned with waste disposal and environmental planning and conservation.

Plastics are everywhere. Bags, bank cards, bottles, and even boats can all be made of this celebrated but much-maligned material. Yet most of us know next to nothing about plastics. We do know that they are practical and cheap--but they also represent a huge environmental problem, for they literally take ages to decompose. In this engaging book, E.S. Stevens tells us everything we have always wondered about plastics and of the efforts, in America, Europe, and Asia, to develop a new breed of environmentally friendly plastics. He points to a possible future where plastics will no longer be made of petroleum, but of plants.

The first two chapters assess the increased use of plastics as a relatively new alternative to other materials. The third chapter introduces us to their impact on the environment and strategies for their disposal or recycling. The next two chapters cover basic concepts and terms used in polymer sciences and provide some basic chemistry. With these fundamentals in tow, the author compares how petroleum-based and biological polymers are made, and the various ways in which they decompose. He acquaints readers with the emerging technologies, their commercial viability, and their future. Finally, instructions are given for preparing basic bioplastics using readily available materials.

Nonspecialists will find "Green Plastics" a concise introduction to this exciting interdisciplinary topic--an introduction otherwise not available. For students it provides easy entry to an area of science with wide appeal and current importance; for teachers, excellent background reading for courses in various sciences. The prospect of depleted fossil fuel supplies, and the potential benefits of bioplastics to the environment and to rural areas that could supply the raw materials, make this book a compelling presentation of a subject whose time has come.
