Shape memory polymers (SMPs) are smart materials that, as a result of an external stimulus such as temperature, can change from a temporary deformed shape back to an original shape. SMPs are finding an increasing use in such areas as clothing where they respond dynamically to changes in heat and moisture levels, ensuring greater comfort for the wearer. Shape memory polymers and textiles provides an authoritative and comprehensive review of these important new materials and their applications. After an introductory chapter on the concept and definition of shape memory materials, the book reviews methods for synthesising, characterising and modelling SMPs. It goes on to consider the properties of particular materials such as shape memory polyurethane and environmentally-sensitive polymer gels. The book concludes by assessing potential applications such as wrinkle-free fabrics and smart fabrics providing improved protection and comfort for the wearer. Shape memory polymers and textiles is a valuable guide to R&D staff in such areas as textile apparel in developing a new generation of smart textiles and other products. Reviews the structure, synthesis and preparation of shape memory polymers Assesses methods for analysing and modelling shape memory properties An authoritative overview of particular fibres such as shape memory polyurethane (SMPU)

Shape memory materials are immensely useful because of their capability to recover their original shapes upon exposure to an external stimulus such as heat, moisture, light or a magnetic field. This book reviews key recent research in shape memory polymers, their properties and applications. Topics include the relationship between morphological structures and shape memory properties; high performance Tg and Tm type shape memory polymers; structures of shape memory polymers with supramolecular switches; and the thermally-active and moisture-active shape memory effect of supermolecular shape memory polymers. Advances in shape memory polymers is an essential reference for polymer and textile material students, scientists, designers, engineers and manufacturers. It is also an invaluable guide for professionals in the biomedical, electronics and engineering industries. Reviews key recent research in shape-memory polymers, their properties and applications Opening chapters address the relationship between morphological structures and shape memory properties and high performance Tg and Tm type shape memory polymers Chapters cover thermally-active and moisture-active shape memory effect of supermolecular shape memory polymers, among other topics

A comprehensive account of the physical / mechanical behaviour of polyurethanes (PU ́s) elastomers, films and blends of variable crystallinity. Aspects covered include the elasticity and inelasticity of amorphous to crystalline PUs, in relation to their sensitivity to chemical and physical structure. A study is made of how aspects of the constitutive responses of PUs vary with composition: the polyaddition procedure, the hard segment, soft segment and chain extender (diols and diamines) are varied systematically in a large number of systems of model and novel crosslinked andthermoplastic PUs. Results will be related to: microstructural changes, on the basis of evidence from x-ray scattering (SAXS and WAXS), and also dynamic mechanical analyses (DMA), differential scanning calorimetry (DSC) and IR dichroism. Inelastic effects will be investigated also by including quantitative correlations between the magnitude of the Mullins effect and the fractional energy dissipation by hysteresis under cyclic straining, giving common relations approached by all the materials studied. A major structural feature explored is the relationship between the nature of the hard segment (crystallising or not) and that of the soft segments. Crystallinity has been sometimes observed in the commercial PUs hard phase but this is usually limited to only a few percent for most hard segment structures when solidified from the melt. One particular diisocyanate, 4,4’-dibenzyl diisocyanate (DBDI) that, in the presence of suitable chain extenders ( diols or diamines), gives rise to significant degrees of crystallinity [i-iii] and this is included in the present work. Understanding the reaction pathways involved, in resolving the subtle morphological evolution at the nanometre level, and capturing mathematically the complex, large-deformation nonlinear viscoelastic mechanical behaviour are assumed to bring new important insights in the world basic research in polyurethanes and towards applied industrial research in this area.
