Shape-memory polymers (SMP) are a unique branch of the smart materials family which are capable of changing shape on-demand upon exposure to external stimulus. The discovery of SMP made a significant breakthrough in the developments of novel smart materials for a variety of engineering applications, superseded the traditional materials, and also influenced the current methods of product designing. This book provides the latest advanced information of on-going research domains of SMP. This will certainly enlighten the reader to the achievements and tremendous potentials of SMP. The basic fundamentals of SMP, including shape-memory mechanisms and mechanics are described. This will aid reader to become more familiar with SMP and the basic concepts, thus guiding them in undergoing independent research in the SMP field. The book also provides the reader with associated challenges and existing application problems of SMP. This could assist the reader to focus more on these issues and further exploit their knowledge to look for innovative solutions. Future outlooks of SMP research are discussed as well. This book should prove to be extremely useful for academics, R&D managers, researcher scientists, engineers, and all others related to the SMP research.

Polymers are the only material that can act as matrices for the incorporation of the widest range of ceramics, nanotubes, nanoparticles, as well as a variety of short and continuous fibres, to create new building and structural materials. Polymer science and technology is a fast growing and dynamic area of study. With this in mind, the author has followed a multidisciplinary approach covering major contemporary advancements in the subject. Largely self-contained, the book includes all essential aspects of the topic such as: polymer nanocomposites, electrospinning, and polymers in electronic applications. It offers extensive guidance on fly-ash-based polymer composites, conducting polymers, shape memory polymers, and thermoset polymer nanocomposites. There is also a review chapter on thermoplastic elastomers based on block copolymers and dynamically cured rubber-plastic blends. Ferroelectric polymer nanocomposites, polymer-based dielectrics, organic field effect transistors, super hydrophobic polymers, and biopolymers are also extensively covered. The content has been classified into six sections of polymer materials and technology: novel polymer composites, nano polymer technology, micro-macro-nano testing and characterization of polymers, speciality polymers, bio-based and biocompatible polymer materials, and new polymer applications. The book is aimed specifically at graduate students and researchers engaged in the study of polymer science and engineering and generically at those studying mechanical engineering, chemical engineering, materials science, and engineering, as well as related industry professionals.

This book covers biodevices, mainly implantable or quirurgical, for the diagnosis or treatment of different pathologies, which benefit from the use of active materials as sensors or actuators. Such active or "intelligent" materials are capable of responding in a controlled way to different external physical or chemical stimuli by changing some of their properties. These materials can be used to design and develop sensors, actuators, and multifunctional systems with a large number of applications for developing biodevices and medical appliances. Current work on these fields entails problems related to synthesis, characterization, modeling, simulation, processing, and prototyping technologies, as well as device testing and validation, all of which are treated in depth in this book, for the several types of active or intelligent materials covered. The research presented in this book helps further development of medical devices, based on the additional functionalities that the use of active or "intelligent" materials, both as sensors and actuators, supplies. The main results exposed may help with the industrial expansion of this kind of materials as part of more complex systems.

In this book, the self-healing of composite structures withshape memory polymer as either matrix or embedded suture issystematically discussed. Self-healing has been well known inbiological systems for many years: a typical example is theself-healing of human skin. Whilst a minor wound can be self-closedby blood clotting, a deep and wide cut needs external help bysuturing. Inspired by this observation, this book proposes atwo-step close-then-heal (CTH) scheme for healing wide-openedcracks in composite structures–by constrained shape recoveryfirst, followed by molecular healing. It is demonstrated that theCTH scheme can heal wide-opened structural cracks repeatedly,efficiently, timely, and molecularly. It is believed thatself-healing represents the next-generation technology and willbecome an engineering reality in the near future. The book consists of both fundamental background and practicalskills for implementing the CTH scheme, with additional focus onunderstanding strain memory versus stress memory and healingefficiency evaluation under various fracture modes. Potentialapplications to civil engineering structures, including sealant forbridge decks and concrete pavements, and rutting resistant asphaltpavements, are also explored. This book will help readers tounderstand this emerging field, and to establish a framework fornew innovation in this direction. Key features: explores potential applications of shape memory polymers incivil engineering structures, which is believed to be unique withinthe literature balanced testing and mathematical modeling, useful for bothacademic researchers and practitioners the self-healing scheme is based on physical change of polymersand is written in an easy to understand style for engineeringprofessionals without a strong background in chemistry
