Polymers are used in many everyday technologies and their degradation due to environmental exposure has lead to great interest in materials which can heal and repair themselves. In order to design new self healing polymers it's important to understand the fundamental healing mechanisms behind the material. Healable Polymer Systems will outline the key concepts and mechanisms underpinning the design and processing of healable polymers, and indicate potential directions for progress in the future development and applications of these fascinating and potentially valuable materials. The book covers the different techniques developed successfully to date for both autonomous healable materials (those which do not require an external stimulus to promote healing) and rehealable or remendable materials (those which only recover their original physical properties if a specific stimulus is applied). These include the encapsulated-monomer approach, reversible covalent bond formation, irreversible covalent bond formation and supramolecular self-assembly providing detailed insights into their chemistry. Written by leading experts, the book provides polymer scientists with a compact and readily accessible source of reference for healable polymer systems.

Polymer Thermodynamics: Blends, Copolymers and Reversible Polymerization describes the thermodynamic basis for miscibility as well as the mathematical models used to predict the compositional window of miscibility and construct temperature versus volume-fraction phase diagrams. The book covers the binary interaction model, the solubility parameter approach, and the entropic difference model. Using equation of state (EOS) theories, thermodynamic models, and information from physical properties, it illustrates the construction of phase envelopes. The book presents nine EOS theories, including some that take into account molecular weight effects. Characteristic values are given in tables. It uses the binary interaction model to predict the compositional window of miscibility for copolymer/homopolymer blends and blends of copolymers and terpolymers with common monomers. It discusses Hansen fractional solubility parameter values, six phase diagram types, the role of polymer architecture in phase behavior, and the mathematical framework for multiple glass transition temperatures found in partially miscible polymer blends. The author also illustrates biomedical and commercial applications of nanocomposites, the properties of various polymer alloys, Fick's laws of diffusion and their implications during transient events, and the use of the dynamic programming method in the sequence alignment of DNA and proteins. The final chapter reviews the thermodynamics of reversible polymerization and copolymerization. Polymer blends offer improved performance/cost ratios and the flexibility to tailor products to suit customers' needs. Exploring physical phenomena, such as phase separation, this book provides readers with methods to design polymer blends and predict the phase behavior of binary polymer blends using desktop computers.

This book focuses on inorganic nanosheets, including various oxides, chalcogenides, and graphenes, that provide two-dimensional (2D) media to develop materials chemistry in broad fields such as electronics, photonics, environmental science, and biology.

This new book explores the consideration of relationships that connect the structural and basic mechanical properties of polymeric mediums within the frameworks of fractal analysis with cluster model representations attraction. Incidentally, the choice of any structural model of medium or their combinations is defined by expediency and further usage convenience only. This book presents leading-edge research in this rapidly changing and evolving field. The book presents descriptions of the main reactions of high-molecular substances within the frameworks of fractal analysis and irreversible aggregation models. Synergetics and percolation theory were also used. In spite of the enormous number of papers dealing with the influence of the medium on the rate of chemical reactions (including synthesis of polymers), no strict quantitative theory capable of "universal" application has been put forward up until now. It is now possible to describe the relationship between the reaction rate constants and the equilibrium constants with the nature of the medium in which the reactions take place by means of a single equation. This important book for the first time gives structural and physical grounds of polymers synthesis and curing, and the fractal analysis is used for this purpose. This new book: * Highlights some important areas of current interest in polymer products and chemical processes * Focuses on topics with more advanced methods * Emphasizes precise mathematical development and actual experimental details * Analyzes theories to formulate and prove the physicochemical principles * Provides an up-to-date and thorough exposition of the present state of the art of complex polymeric materials

Pedagogical Cases in Physical Education and Youth Sport is a completely new kind of resource for students and practitioners working in physical education or youth sport. The book consists of 20 richly described cases of individual young learners, each written by a team of authors with diverse expertise from across the sport, exercise and movement sciences. These cases bring together knowledge from single sub-disciplines into new interdisciplinary knowledge to inform best practice in physical education, teaching and coaching in youth sport settings. At the heart of each case is an individual young person of a specified age and gender, with a range of physical, social and psychological characteristics. Drawing on current research, theory and empirical data from their own specialist discipline, each chapter author identifies the key factors they feel should be taken into account when attempting to teach or coach the young person described. These strands are then drawn together at the end of each chapter and linked to current research from the sport pedagogy literature, to highlight the implications for planning and evaluating teaching or coaching sessions. No other book offers such a rich, vivid and thought-provoking set of pedagogical tools for understanding and working with children and young people in sport. This is an essential resource for any student on a physical education, coaching, kinesiology or sport science course, and for any teacher, coach or instructor working in physical education or youth sport.

Molecular imprinting is one of the most efficient methods to fabricate functional polymer structures with pre-defined molecular recognition selectivity. Molecularly imprinted polymers (MIPs) have been used as antibody and enzyme mimics in a large number of applications. The outstanding stability and straightforward preparation make MIPs ideal substitutes for biologically derived molecular recognition materials, especially for development of affinity separation systems, chemical sensors and high selectivity catalysts. New MIP materials are being increasingly applied to solve challenging problems in environmental sciences, food safety control, biotechnology and medical diagnostics.

Development in molecular imprinting research over the past decade has enabled tailor-designed molecular recognition sites to be created in synthetic materials with physical dimensions in the micro- and nano-regime. The new breakthroughs in MIP synthesis/fabrication have brought in many unprecedented functions of the micro- and nano-structured polymers. The aim of this review volume is to introduce to the readers the new developments in molecularly imprinted micro- and nano-structures, and the new applications that have been made possible with the new generation of imprinted materials.

"... Giant molecules are important in our everyday life. But, as pointed out by the authors, they are also associated with a culture. What Bach did with the harpsichord, Kuhn and Flory did with polymers. We owe a lot of thanks to those who now make this music accessible ..."Pierre-Gilles de Gennes Nobel Prize laureate in Physics (Foreword for the 1st Edition, March 1996)This book describes the basic facts, concepts and ideas of polymer physics in simple, yet scientifically accurate, terms. In both scientific and historic contexts, the book shows how the subject of polymers is fascinating, as it is behind most of the wonders of living cell machinery as well as most of the newly developed materials. No mathematics is used in the book beyond modest high school algebra and a bit of freshman calculus, yet very sophisticated concepts are introduced and explained, ranging from scaling and reptations to protein folding and evolution. The new edition includes an extended section on polymer preparation methods, discusses knots formed by molecular filaments, and presents new and updated materials on such contemporary topics as single molecule experiments with DNA or polymer properties of proteins and their roles in biological evolution.

Functional, flexible and lightweight products are in high demand for modern technologies ranging from microelectronics to energy storage devices. The majority of polymers are thermal and electrical insulators, which hinder their use in these applications. The conductivity of polymers can be significantly enhanced by the incorporation of conducting inorganic nanoparticles. However, this relies not only on the structure and function of the inorganic particles, but is highly determined by the morphology and dispersion of the nanoparticles, interfacial interactions and fabrication technologies of the composites. This book highlights the synthesis, chemistry and applications of two-dimensional (2D) inorganic nanoplatelets in polymer nanocomposites. Chapters cover technical challenges, such as surface functionalisation, compatibilization, interfacial interaction, dispersion, and manufacturing technologies of the polymer nanocomposites. The book also discusses the applications of these polymer nanocomposites in electronics and energy storage. With contributions from global experts, the book provides a much-needed overview of the field, giving advanced undergraduates, postgraduates and other researchers with a convenient introduction to the topic.
