The aim of this work is to develop novel shape memory polymers (SMPs) and nanocomposites for potential biological applications. A kind of commercial SMP, shape memory polyurethane (SMPU), was used to prepare nanocomposites by incorporating nano-clay into the SMPU substrate. The mechanical behaviour, thermal property and shape memory efficiency were studied with various nanofiller loadings. Chemical synthesis methods were also employed to prepare the other designable SMP and its nanocomposites, i.e. the shape memory polystyrene co-polymer (SMPS). Multiple technologies were adopted to enhance the SMPS matrix such as modifying the chemical components, introducing various functional nanoparticles into the polymeric network and improving the dispersion of the nanoparticles. Different methods were used to characterize the overall performance of the obtained materials. Mechanical tests were performed at different dimensional scales with a varied degree of localisation. Nanoindentation was firstly applied to assess the micro-mechanical properties of shape memory polymer nanocomposites at scales down to particle size. The micro-mechanical analysis provided the fundamental information on the SMPs and their nanocomposites for bio-MEMS applications. Potential applications were also explored through manufacturing different type of device models and testing their shape recovery efficiencies. Finally, theoretical contributions were made in two areas. The first one was the theoretical analysis on the nanoparticles enhancement to the soft polymeric matrix. The other was in developing a constitutive model to describe the thermo-viscoelastic property and shape memory behaviour for SMP nanocomposites.

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 Polymer derived Nanocomposites: Features to Cutting-Edge Advancements summarizes the up-to-date of fundamentals and applications of the shape memory polymer derived nanocomposites. Design and fabrication of shape memory polymeric nanocomposites have gained significant importance in the field of up-to-date nano/materials science and technology. In recent times, the shape memory polymers and nanocomposites have attracted considerable academic and industrial research interest. This feature book will present a state-of-the-art assessment on the versatile shape memory materials. The flexibility, durability, heat stability, shape deformability, and shape memory features of these polymers have shown dramatic improvements with the nanofiller addition. Appropriate choice of the stimuli-responsive polymer, nanofiller type and content, and fabrication strategies may lead to enhanced physicochemical features and stimuli-responsive performance. Several successful stimuli-responsive effects have been achieved in the shape memory nanocomposites such as thermo-responsive, electro-active, photo-active, water/moisture-responsive, pH-sensitive, etc. Consequently, the shape memory polymer based nanocomposites have found applications in high-tech devices and applications. This book initially offers a futuristic knowledge regarding indispensable features of the shape memory polymeric nanocomposites. Afterwards, the essential categories of the stimuli-responsive polymer-based nanocomposites have been discussed in terms of recent scientific literature. Subsequent sections of this book are dedicated to the potential of shape memory polymer-based nanocomposite in various technical fields. Significant application areas have been identified as foam materials, aerospace, radiation shielding, sensor, actuator, supercapacitor, electronics and biomedical relevance. The book chapters also point towards the predictable challenges and future opportunities in the field of shape memory nanocomposites. Provides the essentials of shape memory polymeric nanocomposites Includes important categories of shape memory nanocomposites Presents current technological applications of shape memory polymers and derived nanocomposite in sponges, aerospace, EMI shielding, ionizing radiation shielding, sensors, actuator, supercapacitor, electronics, and biomedical fields

This book presents a thorough discussion of the physics, biology, chemistry and medicinal science behind a new and important area of materials science and engineering: polymer nanocomposites. The tremendous opportunities of polymer nanocomposites in the biomedical field arise from their multitude of applications and their ability to satisfy the vastly different functional requirements for each of these applications. In the biomedical field, a polymer nanocomposite system must meet certain design and functional criteria, including biocompatibility, biodegradability, mechanical properties, and, in some cases, aesthetic demands. The content of this book builds on what has been learnt in elementary courses about synthesising polymers, different nanoparticles, polymer composites, biomedical requirements, uses of polymer nanocomposites in medicine as well as medical devices and the major mechanisms involved during each application. The impact of hybrid nanofillers and synergistic composite mixtures which are used extensively or show promising outcomes in the biomedical field are also discussed. These novel materials vary from inorganic/ceramic-reinforced nanocomposites for mechanical property improvement to peptide-based nanomaterials, with the chemistry designed to render the entire material biocompatible.
