Presenting an overview of polymer nanocomposites, how they compare with traditional composites, and their increasing commercial importance, Multifunctional Polymer Nanocomposites conveys the significance and various uses of this new technology for a wide audience with different needs and levels of understanding. Exploring definitions, architectures, applications, and fundamental principles of various functions of multifunctional polymeric smart materials—from bulk to nano— this book covers the use of multifunctional polymer nanocomposites in— •carbon nanotubes •electroactive and shape memory polymers •magnetic polymers •biomedical and bioinformation applications •fire-resistance treatments •coating technologies for aeronautical applications •ocean engineering A practical analysis of functional polymers, nanoscience, and technology, this book integrates coverage of fundamentals, research and development, and the resulting diversity of uses for multifunctional polymers and their nanocomposites. Quite possibly the first reference of its kind to explore the progress of polymer nanocomposites in terms of their multifunctionality, it covers both theory and experimental results regarding the relationships between the effective properties of polymer composites and those of polymer matrices and reinforcements. This book is a powerful informational resource that illustrates the importance of polymer nanomaterials, examining their applications in various sectors to promote new, novel research and development in those areas. It will be a welcome addition to the libraries of not only engineering researchers, but senior and graduate students in relevant fields.

Ocean Engineering Application of Nanocomposites 423 Yansheng Yin and Xueting Chang vii © 2011 by Taylor & Francis Group, LLC Preface A nanocomposite is a multiphase solid material in which one of the phases has one, two, or three dimensions smaller than 100 nanometers, or structures having nano-scale repeat distances between the different phases that make up the material (Nanocomposite Science and Technology, Wiley, 2003). Nano inorganic or organic powders or lms with special physical properties are combined with polymers to form polymer nanocomposites whose physical properties and mechanical performance differ from those of the component materials signicantly. A primary purpose of producing polymer nanocom- posites is to impart the composites with multifunctional properties. There has been a rapid development of multifunctional polymer nanocompos- ites and a number of achievements have been reported. Due to their novel properties, multifunctional polymer nanocomposites can be used in a broad range of applications from outer space to automobiles, and to address chal- lenges in organic solar cells, and biological technologies. The book is aimed at audiences at different levels to provide a compre- hensive discussion of multifunctional polymer nanocomposites. Both the- oretical work and experimental results on the relationships between the effective properties of polymer composites and the properties of polymer matrices and reinforcements are discussed. Chapter 1 presents the over- view of the development from bulk to nano for academics and industries, the importance of understanding the role of the nano and multifunctional polymer composites in denition, fabrication, design, nanotechnology, and nano products, and the increasing trend of using nano and multifunctional polymer composites. Chapter 2 gives a comprehensive review on the structural properties of nanotubes and their related polymer composites. Many key factors such as dispersion, interfacial bonding characteristics, novel types of nanotubes in relation to the resultant mechanical, electrical, and thermal properties of the composites are discussed and analyzed through theoretical and computa- tional studies. Chapter 3 provides some recent advances in multifunctional polymeric smart materials, including electroactive polymers and shape mem- ory polymers and their composites. A comprehensive discussion is devoted to the denitions, architectures, applications, and fundamental principles of various functions of multifunctional polymeric smart materials. viii Preface © 2011 by Taylor & Francis Group, LLC Chapter 4 reviews the development of magnetic polymer nanocomposites. Their fabrication, processing, and physicochemical property analyses are taken into account. The effect of magnetic oxide nanoparticles on the chemi- cal polymerization of polymer matrices is investigated. The morphology (size and shape) and other physicochemical properties of the polymer matrix are signicantly inuenced by the magnetic oxide nanoparticles. Chapter 5 focuses on the nanomechanics of carbon nanotubes and modeling of carbon nanotube-based composites. This chapter introduces the atomistic modeling technique, the modeling of electromechanical coupling behaviors of carbon nanotubes, and the modeling of electrical conductiv- ity of nanotube-based composites. Furthermore, the relevant experimental studies are also introduced. Chapter 6 presents the development of conven- tional biomaterials to the state-of-the-art biocomposites for biomedical and bioengineering applications. The advantages and disadvantages of different types of biomaterials, their material properties, structures, biodegradability and biocompatibility to the host body, and applications of the biocomposites are given. Chapter 7 provides the advances in synthesis, processing and test- ing of condensed phase ame retardant polymer nanocomposites. The mor- phologies, thermal stability, ammability, and char formation of polymer composites coated with carbon nanopaper are studied. The re retardant mechanism of carbon nanopaper is discussed. Chapter 8 follows the nanomaterials through engineering to applications and focuses on the recent development of polymer nanocomposites coatings for aeronautical applications. This provides an informative account of the challenges and opportunities for nanocomposite coatings in aeronautical operations under conditions such as lightning strike, erosion, ice accretion, and environmental corrosion. Chapter 9 describes the surface modication of carbon nanotubes for composites, which includes chemical modica- tion, substitution reaction, electrochemical modication, and photochemi- cal modication. Chapter 10 describes the ocean engineering application of nanocomposites, dealing with deformation, damage initiation, damage growth, and failure and corrosion in nanopaticles. Multifunctional Polymer Nanocomposites provides the reader with the latest thinking on polymer nanocomposites by the scientists and researchers actu- ally involved in their development. This book will be a useful reference not only for engineering researchers, but also for senior and graduate students in their relevant elds.
