Shape memory polymers and textiles
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 will be a valuable guide to R&D staff in such
areas as textile apparel in developing a new generation of smart textiles and other
products.
