This text follows a broad sequence of preparation, characterization, physical and mechanical properties and structure-property relations. Polymers: Chemistry and Physics of Modern Materials, Second Edition covers several methods of polymerization, properties, and advanced applications such as liquid crystals and polymers used in the electronics industry. Topics also include Step-Growth, Free Radical Addition, and Ionic Polymerization; Copolymerization; Polymer Stereochemistry and Characterization; Structure-Property Relationship; Polymer Liquid Crystals; and Polymers for the Electronics Industry.

Polymers have generated considerable interest in a large number of technologically important fields such as human healthcare systems. Polymers represent a very important domain of materials and have become an integral part of day to day human life. Polymers exist in nature; they have been and continue to be an integral part of the universe. This book is intended for scientists and researchers to use in their research or in their professional practice in polymer chemistry and its biomedical applications. Multiple biological, synthetic and hybrid polymers are used for multiple medical applications. A wide range of different polymers are available, and they have the advantage to be tunable in physical, chemical and biological properties and in a wide range to match the requirements of specific applications. This book gives a brief overview about the introduction and developments of polymers for different applications. The biomedical polymers comprise not only bulk materials, but also coatings and pharmaceutical nano-carriers for drugs. The surface modification of the inorganic nanoparticles with a physically or chemically end-tethered polymer chain has been employed to overcome the problems associated with the polymers. Chemically attached polymer chains not only stabilize the inorganic nanoparticles, but also lead to photosensitivity, bioactivity, biocompatibility and pharmacological properties in the composites. Polymer encapsulated silica nanocomposites (mesoporous) have potential applications in different fields, such as optics, bio-catalysis, microelectronics bone tissue engineering, coatings cosmetics, inks, agriculture, drug release systems, diagnoses, enzyme imaging, temperature-responsive materials, and thermosensitive vehicles for cellular imaging. Polymer grafted nanosized particles are known to have excellent properties such as good dispersion ability in solvents and polymer matrices. Polymer-based controlled drug delivery systems have some specific advantages, such as improved efficiency and reduced toxicity. The incorporation of a thermoresponsive polymer layer often enhances protein absorption and specific biomolecular tagging through hydrogen bonding. As a result, the nanocomposite gets cleared from the body at a faster rate (blood residence becomes low). This book is composed of fourteen edited chapters; it is intended for scientists and researchers to use in their research or in their professional practice in polymer chemistry and its biomedical applications.

With contributions from top nanoscientists, this book offers a global perspective on the latest developments in nanotechnology. It covers the major themes of nanoscience and nanotechnology, addressing many of the major issues, from concept to technology to implementation. It is an important reference publication that provides new research and updates on a variety of nanoscience uses through case studies and supporting technologies, and it also explains the conceptual thinking behind current uses and potential uses not yet implemented. International experts with countless years of experience lend this volume credibility.

A classical metastable state possesses a local free energy minimum at infinite sizes, but not a global one. This concept is phase size independent. We have studied a number of experimental results and proposed a new concept that there exists a wide range of metastable states in polymers on different length scales where their metastability is critically determined by the phase size and dimensionality. Metastable states are also observed in phase transformations that are kinetically impeded on the pathway to thermodynamic equilibrium. This was illustrated in structural and morphological investigations of crystallization and mesophase transitions, liquid-liquid phase separation, vitrification and gel formation, as well as combinations of these transformation processes. The phase behaviours in polymers are thus dominated by interlinks of metastable states on different length scales. This concept successfully explains many experimental observations and provides a new way to connect different aspects of polymer physics.* Written by a leading scholar and industry expert* Presents new and cutting edge material encouraging innovation and future research* Connects hot topics and leading research in one concise volume
