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 کاملShape memory-based multifunctional structural actuator panels
A multifunctional panel concept is presented in which a lightweight, structural sandwich panel is able to undergo a reversible change in shape upon application of a localized thermal stimulus. The shape change is effected by metallic (or polymeric) shape memory (SM) face sheet elements, which exploit a “one-way” SM effect only. Unlike other designs, no external or bias forces are required to co...
متن کاملSynthesis of some network polymers with siloxane units as a drug delivery system
New biodegradable network polymers containing siloxane-linked polymeric prodrugs of 5-ammino-2-hydroxybenzoic acid (5-ASA) in the main chain were prepared by ter polymerization of methacrylic acid (MA), 2-hydroxyethylmethacrylate (HEMA), and bis (trimethylsilyloxy) methylsilane (VBM) in the presence of some new cross-linking agents.The monomers and polymers were characterized by FT-IR and 1H-NM...
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;))...
