Polymer-clay nanocomposites have flame-retardant, antimicrobial, anticorrosion and self-healing properties, they are biocompatible and environmentally benign. Multiple types of clay minerals may be exfoliated or individually dispersed and then used as natural nanoparticle additives of different size and shape for composite formation. Loading polymers with clays increases their strength, however, it is only recently that such composites were prepared with controlled nanoscale organization allowing for the enhancement of their mechanical properties and functionality. Edited by pioneers in the field, this book will explain the great potential of these materials and will bring together the combined physico-chemical, materials science and biological expertise to introduce the reader to the vibrant field of nanoclay materials. This book will provide an essential text for materials and polymers scientists in industry and academia.

This book covers smart polymer nanocomposites with perspectives for application in energy harvesting, as self-healing materials, or shape memory materials. The book is application-oriented and describes different types of polymer nanocomposites, such as elastomeric composites, thermoplastic composites, or conductive polymer composites. It outlines their potential for applications, which would meet some of the most important challenges nowadays: for harvesting energy, as materials with the capacity to self-heal, or as materials memorizing a given shape.The book brings together these different applications for the first time in one single platform. Chapters are ordered both by the type of composites and by the target applications. Readers will thus find a good overview, facilitating a comparison of the different smart materials and their applications. The book will appeal to scientists in the fields of chemistry, material science and engineering, but also to technologists and physicists, from graduate student level to researcher and professional.

ABSTRACT: Damage continues to plague the structural integrity of polymer composites. Continued stress leads to cracking and weakening of a composite system. Engineering polymer composites with carbon nanotube reinforcements and self-healing capabilities can potentially enhance the composites properties and extend the service lifetime. Carbon nanotubes (CNTs) promise to improve the electrical and mechanical properties of composite materials into which they are incorporated. These hollow tubes comprised completely of carbon, which have nanometer scale diameters, as well as low density, possess unique paradigm-shifting mechanical and electrical properties. The major problem prohibiting the widespread use of enhanced polymer composites has been the difficulty fabricating these composites. Research in developing methods capable of fully integrating the components is essential. This study sought to develop fabrication strategies to overcome the problem of integration and create polymer composites with advanced behavior useful in multiple applications. Engineering polymer composites with CNT and self-healing capabilities could enhance the composites' properties and extend the lifetime. Polymer composites are prone to degradation and damage. The damage leads to major system failure. The strategy developed here was inspired by living systems that evolved to mend damage and regain function. Engineering "smart" synthetic composites with infrastructures which can respond to damage is necessary for improving polymer usefulness. The molecular processes that alleviates damage aids in avoiding total mechanical failure. Such self-healing materials repair damage and continue function post repair. There several methods for creating composites with self-healing capability. The one studied here involves embedded microcapsules whose envelopes burst open releasing their contents in response to the material cracking. Microcapsules containing a reactive liquid "healing" core are embedded in the polymer during fabrication. A mechanical defect in the polymer breaks the shells of the microcapsules releasing the "healing" core. The core material polymerizes, thus healing the crack. As defects are repaired, functionality should be restored and the serviceable lifetime extended. The results obtained in this study indicate microcapsules can be modified to incorporate CNT. Also self-healing capabilities can be extended to new polymer systems in a cost-effective manner. In addition to enhancing polymers for sustainability, CNT reinforced structural foams could also prove to be beneficial in numerous industrial applications, where mechanically strong foams are needed. CNTs are already being investigated as structural enhancements for other foams, such as polyurethane - the most common and widely used polymer. High internal phase emulsion foams, highly porous emulsion template foams, are emerging as new and important forms of microcellular foams with numerous advantages, such as high impact strength and high stiffness-to-weight ratio. This research developed a novel method for creating carbon nanotube reinforced microcellular foam.

Self-healing is a well-known phenomenon in nature: a broken bone merges after some time and if skin is damaged, the wound will stop bleeding and heals again. This concept can be mimicked in order to create polymeric materials with the ability to regenerate after they have suffered degradation or wear. Already realized applications are used in aerospace engineering, and current research in this fascinating field shows how different self-healing mechanisms proven successful by nature can be adapted to produce even more versatile materials. The book combines the knowledge of an international panel of experts in the field and provides the reader with chemical and physical concepts for self-healing polymers, including aspects of biomimetic processes of healing in nature. It shows how to design self-healing polymers and explains the dynamics in these systems. Different self-healing concepts such as encapsulated systems and supramolecular systems are detailed. Chapters on analysis and friction detection in self-healing polymers and on applications round off the book.
