Abstract

Shape-memory materials are a class of “smart” materials that have the capability to change from a temporary shape to a memorized permanent shape upon application of an external stimulus. In particular, shape-memory polymers (SMPs) represent a cheap and efficient alternative to well-known metallic shape-memory alloys because they are relatively easy to manufacture and program. Thermally induced SMPs are the most extensively investigated group of SMPs. The use of SMPs as self-repairing or rewritable materials has found growing interest in environmentally friendly technologies. In this chapter, we review different types of shape-memory material, which have been developed in the last few decades.

Keywords
