This paper describes a new kind of zwitterionic copolymer having a multi-shape memory effect and a moisture-sensitive shape memory effect from DMAPS and acrylic acid (AA). In addition to dual-SME, the copolymer also shows triple-SME and quadruple-shape-memory effect.

Effects of density and cell morphologies on the shape memory effect of a porous shape memory polymer
SPIE Proceedings, 2007This paper investigates the effects of different densities and cellular morphologies on the shape memory effect (SME) of a porous shape memory polymer (SMP). The batch foaming processing technique was employed to obtain the desired foamed cellular structures.

Understanding shape memory requires a thermodynamic approach that takes into account the structure of the solid and the mechanical properties resulting from it. For this reason, the crystallographic and thermodynamic aspects of shape memory effects will be discussed below to the extent to which they are relevant to the development of microactuators ...

Abstract We are now in a position to discuss the shape-memory effect. Recall from the introduction that this is the ability of certain materials to recover, on heating, apparently plastic deformation sustained below a critical temperature.

Theory of pseudoelasticity and the shape-memory effect
Physical Review B, 1992A theory of pseudoelasticity has been developed in the phenomenological Ginzburg-Landau scheme. The system characterized by «stripe»-type ferroelastic domain structure has been discussed using the transfer-integral method, which directly gives the equilibrium density of domain boundaries and the response of domain pattern against the external stress ...

Shape memory effect of antiferroelectrics
Ferroelectrics, 2001Abstract Pb(Zr0.95 Ti0.05)O3 (PZT) antiferroelectric ceramics have been fabricated by sintering and their structure and phase transition behavior were studied by X-ray diffraction (XRD) and Differential Scanning Calorimetry (DSC). The phase transition order is anti-ferroelectric (ARE) → ferroelectric (FE) → Paraelectric with structure changes ...

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 ...

Shape memory effect in FeMnNiAl iron-based shape memory alloy
Scripta Materialia, 2019Abstract The development of Iron-based shape memory alloys holds significant promises for cost-sensitive applications. FeMnNiAl has been attracting increasing interest due to high levels of superelasticity across a wide range of temperatures (−196–300 °C). However, shape memory effect for this alloy system has not been demonstrated.

Phase transition of shape-memory effect in glassy shape-memory polymers
SPIE Proceedings, 2013Shape-memory materials (SMMs) are fascinating materials, with the potential for application as “smart materials” and also as actively moving materials, which can change their shape in a predefined way between/among shapes in presence of an appropriate stimulus.
