As an important member of the smart materials family, shape memory polymers have attracted serious attention as a result of their ability to recover their original shape after having a stimulus applied to them. From their history to the most recent developments, this book provides the full story of polyurethane-based shape memory polymers, including discussion of thermomechanical properties and behavior of the polymer and its composites. Next, it addresses the modification of the shape memory polymer and introduces novel actuation mechanisms. Finally, the author presents a spectrum of...
