Shape Memory Polymers For Biomedical Applications

Shape memory polymers (SMPs) are an emerging class of smart polymers which give scientists the ability to process the material into a permanent state and predefine a second temporary state which can be triggered by different stimuli. The changing chemistries of SMPs allows scientists to tailor important properties such as strength, stiffness, elasticity and expansion rate. Consequently SMPs are being increasingly used and developed for minimally invasive applications where the material can expand and develop post insertion. This book will provide readers with a comprehensive review of shape memory polymer technologies. Part 1 will discuss the fundamentals and mechanical aspects of SMPs. Chapters in part 2 will look at the range of technologies and materials available for scientific manipulation whilst the final set of chapters will review applications. Reviews the fundamentals of shape memory polymers with chapters focussing on the basic principles of the materials Comprehensive coverage of design and mechanical aspects of SMPs Expert analysis of the range of technologies and materials available for scientific manipulation

Shape memory polymers (SMPs) are some of the most important and valuable engineering materials developed in the last 25 years. These fascinating materials demonstrate remarkably versatile properties—including capacity for actuation and stimulus responsiveness—that are enabling technologists to develop applications used to explore everything from the outer reaches of space to the inside of the human body. Polyurethane Shape Memory Polymers details the fundamentals of SMP makeup, as well as their shape-recovery features and their seemingly endless potential for use in applications ranging from the macro- to submicron scales. With an abundance of illustrations and vivid pictures to explain how SMPs and their composites work and how they can be used, this book covers: History and most recent developments in SMPs Thermomechanical properties and behavior of the polymers and their composites Modification of SMPs and novel actuation mechanisms Large-scale surface pattern generation Multi-shape memory effect Fabrication techniques Characterization of composites A must-have reference for anyone working in the materials science and engineering fields, this book outlines the properties—such as light weight, low cost, and ability to handle high strain—that make the easily processed SMPs so useful in fields including aerospace, biomedicine, and textiles. It is intended to help readers understand and apply the knowledge and techniques presented to develop new innovations that will further benefit society.

Shape-Memory Polymer Device Design discusses the latest shape-memory polymers and the ways they have started to transition out of the academic laboratory and into devices and commercial products. Safranski introduces the properties of shape-memory polymers and presents design principles for designing and manufacturing, providing a guide for the R&D engineer/scientist and design engineer to add the shape memory effect of polymers into their design toolbox. This is the first book to focus on applying basic science knowledge to design practical devices, introducing the concept of shape-memory polymers, the history of their use, and the range of current applications. It details the specific design principles for working with shape-memory polymers that don't often apply to mechanically inactive materials and products. Material selection is thoroughly discussed because chemical structure and thermo-mechanical properties are intrinsically linked to shape-memory performance. Further chapters discuss programming the temporary shape and recovery through a variety of activation methods with real world examples. Finally, current devices across a variety of markets are highlighted to show the breadth of possible applications. Demystifies shape-memory polymers, providing a guide to their properties and design principles Explores a range of current and emerging applications across sectors, including biomedical, aerospace/automotive, and consumer goods Places shape-memory polymers in the design toolkit of R&D scientists/engineers and design engineers Discusses material selection in-depth because chemical structure and thermo-mechanical properties are intrinsically linked to shape-memory performance

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.
