Shape-memory polymers.
Material scientists predict a prominent role in the future for self-repairing and intelligent materials. Throughout the last few years, this concept has found growing interest as a result of the rise of a new class of polymers. These so-called shape-memory polymers by far surpass well-known metallic shape-memory alloys in their shape-memory properties. As a consequence of the relatively easy ma...
متن کاملDesign strategies for shape memory polymers
Shape memory polymers (SMPs) are polymeric materials capable of recovering from a ‘fixed’ temporary shape to a ‘memorized’ permanent shape upon exposure to an external stimulus. Two structural elements are required for a polymer to exhibit useful shape memory: a network structure that defines the permanent shape (the ‘memory’), and a switching segment that induces a significant change in the mo...
متن کاملShape memory polymers for active cell culture.
Shape memory polymers (SMPs) are a class of "smart" materials that have the ability to change from a fixed, temporary shape to a pre-determined permanent shape upon the application of a stimulus such as heat(1-5). In a typical shape memory cycle, the SMP is first deformed at an elevated temperature that is higher than its transition temperature, T(trans;) [either the melting temperature (T(m;))...
متن کاملMedical applications of shape memory polymers.
Shape memory polymers (SMP) are lightweight, have a high strain/shape recovery ability, are easy to process, and required properties can be tailored for variety of applications. Recently a number of medical applications have been considered and investigated, especially for polyurethane-based SMP. SMP materials were found to be biocompatible, non-toxic and non-mutagenic. The glass transition tem...
متن کاملReview of progress in shape-memory polymers
Shape-memory polymers (SMPs) have attracted significant attention from both industrial and academic researchers due to their useful and fascinating functionality. This review thoroughly examines progress in shape-memory polymers, including the very recent past, achieved by numerous groups around the world and our own research group. Considering all of the shapememory polymers reviewed, we ident...
