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.

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 ...

In this contribution, shape memory polymers (SMPs) of chemically-crosslinked zwitterionic polyurethanes (CZPUs) were fabricated by crosslinking of the N,N-bis(2-hydroxyethyl) isonicotinamide (BINA)/hexamethylene diisocyanate (HDI) polyurethanes system by

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 polymers (SMPs) will come to act an indispensable part in numerous aspects of human activity. However, the low mechanical strengths and thermal conductivities of SMPs have largely restricted their applications. Remarkable improvements in the

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.
