Shaping tissue with shape memory materials
Advanced Drug Delivery Reviews, 2013After being severely and quasi-plastically deformed, shape memory materials are able to return to their original shape at the presence of the right stimulus. After a brief presentation about the fundamentals, including various shape memory effects, working mechanisms, and typical shape memory materials for biomedical applications, we summarize some ...

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.

Characristics of Shape Memory Composites Combined with Shape Memory Alloy and Shape Memory Polymer
Advanced Materials Research, 2013In order to develop high functionality of shape memory materials, the shape memory composites combined with TiNi wire and shape memory epoxy were prepared, and the mechanical and thermomechanical properties were studied. The results showed the addition of TiNi wire increased the Young modulus and breaking strength both at room temperature and at ...

Elasticity and Shape Memory Effect of Shape Memory Fabrics
Textile Research Journal, 2008An attempt has been made in this paper to investigate the distinction between shape memory effect and the wrinkle recovery property of cotton fabrics in terms of temperature sensitivity and elasticity. Elasticity is an inherent characteristic of typical wrinkle-free fabrics, because they are suppose to recover after the release of ...

Optimization of the shape memory effect in shape memory polymers
Journal of Polymer Science Part A: Polymer Chemistry, 2011AbstractIn this article, we show that given a thermoresponsive shape memory polymer, it is possible to alter a number of its properties, such as the recovery temperature, shape fixity ratio, maximum recovery stress, and final recovery stress (and even a right combination of some of them, e.g., the maximum recovery stress and final recovery stress ...

Modeling the shape memory effect of shape memory polymer
SPIE Proceedings, 2009Dynamic mechanical analysis (DMA) tests are conducted on the styrene-based shape memory polymer (SMP) to investigate its state transition behaviors. Tensile tests at various constant temperatures are carried out to reveal the stressstrain- temperature relationship of the styrene-based SMP.

A tough shape memory polymer with triple-shape memory and two-way shape memory properties
Journal of Materials Chemistry A, 2014In this study, a tough shape memory polymer network based on polydopamine, poly(e-caprolactone) and diisocyanate was synthesized in three steps. Fourier transform infrared spectroscopy was used to confirm the synthesis process. The tensile tests demonstrated the good mechanical properties of the materials with a tensile modulus and tensile strength ...

Shape-memory alloys are capable of undergoing reversible phase transitions as a result of temperature, pressure, or other stress-related changes. These materials exhibit a mechanical type of shape memory called pseudoelasticity and, under certain conditions, linear superelasticity. The recoverable strain or shape is generally .
