Multi-shape memory effect in shape memory polymer composites
Materials Letters, 2012In this work, the multi shape memory effect is studied for two types of thermal active epoxy polymer composites. One of them is called the controlled behavior of composite material (CBCM) which has already been tested as an unsymmetrical active composite and the other one is the conventional symmetrical composite.

Shape Memory Effect in Quaternary NiTiHfPd Shape Memory Alloys beyond 200 °C
Journal of Materials Engineering and Performance, 2022© 2022, ASM International.In this study, the effects of minor palladium (3 and 5 at.%) addition to ternary NiTiHf shape memory alloy (SMA) were investigated to design a high-temperature NiTiHfPd SMA. While most of the reported NiTiHfPd SMAs contain (Ni+Pd)-rich compositions, the (Ti+Hf)-rich compositions have not been studied to the same extent.

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 an external force ...

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.

Triple Shape Memory Effect of Star-Shaped Polyurethane
ACS Applied Materials & Interfaces, 2014In this study, we synthesized one type of star-shaped polyurethane (SPU) with star-shaped poly(ε-caprolactone) (SPCL) containing different arm numbers as soft segment and 4,4'-diphenyl methane diisocyanate (MDI) as well as chain extender 1,4-butylene glycol (BDO) as hard segment.

Temperature memory effect in amorphous shape memory polymers
Soft Matter, 2014Temperature memory effect in shape memory polymers is found to be complicated and the shape memory characteristic temperature depends on the programming temperature and other programming conditions.

Shape Memory Effect in Cu Nanowires
Nano Letters, 2005A rubber-like pseudoelastic behavior is discovered in single-crystalline face-centered-cubic (FCC) Cu nanowires in atomistic simulations. Nonexistent in bulk Cu, this phenomenon is associated primarily with a reversible crystallographic lattice reorientation driven by the high surface-stress-induced internal stresses due to high surface-to-volume ...

Various shape memory effects of stimuli-responsive shape memory polymers
Smart Materials and Structures, 2013One-step dual-shape memory polymers (SMPs) recover their original (permanent) shape upon small variation of environmental conditions such as temperature, electric field, light, magnetic field, and solvent/chemicals. For advanced applications such as aerospace and medical devices, complicated, multiple-step, spatially controllable, and two-way shape ...
