Shape-Memory Polymers for Biomedical Applications

Advanced Functional Materials, 2020
One of the most promising fields for shape-memory polymers is the biomedical field. Shape-memory polymers that can be triggered by various (physiological) conditions such as temperature and moisture have been reported, as well as remotely triggerable ...

Reprogrammable Recovery and Actuation Behaviour of Shape-Memory Polymers

Nature Reviews Materials, 2019
Shape memory is the capability of a material to be deformed and fixed into a temporary shape. Recovery of the original shape can then be triggered only by an external stimulus.

Medical applications of shape memory polymers

Biomedical Materials, 2007
Shape memory polymers (SMP) are lightweight, have a high strain/shape recovery ability, are easy to process, and required properties can be tailored for variety of applications. Recently a number of medical applications have been considered and investigated, especially for polyurethane-based SMP.

Optimization of the shape memory effect in shape memory polymers

Journal of Polymer Science Part A: Polymer Chemistry, 2011
AbstractIn 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, 2009
Dynamic 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.

Enzymatically triggered shape memory polymers

Acta Biomaterialia, 2019
Cytocompatible shape memory polymers activated by thermal or photothermal triggers have been developed and established as powerful "smart material" platforms for both basic and translational research. Shape memory polymers (SMPs) that could be triggered directly by biological activity have not, in contrast, been reported.

pH‐Induced Shape‐Memory Polymers

Macromolecular Rapid Communications, 2012
AbstractA novel pH sensitive shape‐memory polymer (SMP) is prepared by cross‐linking the β‐cyclodextrin modified alginate (β‐CD‐Alg) and diethylenetriamine modified alginate (DETA‐Alg): The pH reversible β‐CD‐DETA inclusion complexes serve as a reversible phase, and the cross‐linked alginate chains serve as a fixing phase.

Light-induced shape-memory polymers

Nature, 2005
Materials are said to show a shape-memory effect if they can be deformed and fixed into a temporary shape, and recover their original, permanent shape only on exposure to an external stimulus. Shape-memory polymers have received increasing attention because of their scientific and technological significance.
