TLDR
It is discussed how the described shape-memory polymers show great potential for diverse applications, including in the medical arena, sensors, and actuators, and as dictated by macromolecular details.Abstract:
Shape-memory polymers (SMPs) have attracted significant attention from both industrial and academic researchers due to their useful and fascinating functionality. This review thoroughly examines progress in shape-memory polymers, including the very recent past, achieved by numerous groups around the world and our own research group. Considering all of the shape-memory polymers reviewed, we identify a classification scheme wherein nearly all SMPs may be associated with one of four classes in accordance with their shape fixing and recovering mechanisms and as dictated by macromolecular details. We discuss how the described shape-memory polymers show great potential for diverse applications, including in the medical arena, sensors, and actuators.read more

A review of shape memory alloy research, applications and opportunities
TL;DR: Shape memory alloys (SMAs) are a class of shape memory materials (SMMs) which have the ability to "memorise" or retain their previous form when subjected to certain stimulus such as thermomechanical or magnetic variations.

Stimuli-responsive supramolecular polymeric materials.
TL;DR: This critical review of recent developments in supramolecular polymeric materials is addressed, which can respond to appropriate external stimuli at the fundamental level due to the existence of noncovalent interactions of the building blocks.

Shape-memory polymers and their composites: Stimulus methods and applications
TL;DR: Shape-memory polymers (SMPs) undergo significant macroscopic deformation upon the application of an external stimulus (e.g., heat, electricity, light, magnetism, moisture and even a change in pH value).

Tunable polymer multi-shape memory effect
TL;DR: It is shown that the perfluorosulphonic acid ionomer (PFSA), which has only one broad reversible phase transition, exhibits dual-, triple-, and at least quadruple-shape memory effects, all highly tunable without any change to the material composition.

Light-induced shape-memory polymers
TL;DR: Polymers containing cinnamic groups can be deformed and fixed into pre-determined shapes—such as elongated films and tubes, arches or spirals—by ultraviolet light illumination and can recover their original shape at ambient temperatures when exposed to ultraviolet light of a different wavelength.
