Early research of shape memory polymer vascular stents

open access: yeseXPRESS Polymer Letters, 2022
Shape memory polymers (SMPs) are smart materials that can alter their shape from a temporary shape to a permanent shape upon external stimuli. This unique property of SMP has shown enormous potential and breakthrough discoveries in biomedical engineering.

Multidirectional Triple-Shape-Memory Polymer by Tunable Cross-linking and Crystallization

open access: yes, 2020
Medical fixing is one of the very important applications of the shape-memory polymer material, and the two important properties of the medical fixing material are that it perfectly fits the body during the fixing and easily detaches after being used.

Multifunctional Shape‐Memory Polymers [PDF]

open access: yesAdvanced Materials, 2010
AbstractThe thermally‐induced shape‐memory effect (SME) is the capability of a material to change its shape in a predefined way in response to heat. In shape‐memory polymers (SMP) this shape change is the entropy‐driven recovery of a mechanical deformation, which was obtained before by application of external stress and was temporarily fixed by ...

Distributed sensing based real‐time process monitoring of shape memory polymer components [PDF]

open access: yes, 2022
Shape memory polymer (SMP) materials have the capacity to undergo large deformations imposed by mechanical loading, hold a temporary shape, and then recover their original shape upon exposure to a particular external stimulus.

Thermal-mechanical properties of polyurethane-clay shape memory polymer nanocomposites [PDF]

open access: yes, 2010
Shape memory nanocomposites of polyurethane (PU)-clay were fabricated by melt mixing of PU and nano-clay. Based on nano-indentation and microhardness tests, the strength of the nanocomposites increased dramatically as a function of clay content, which is

Some New Concepts of Shape Memory Effect of Polymers [PDF]

open access: yes, 2014
In this study some new concepts regarding certain aspects related to shape memory polymers are presented. A blend of polylactic acid (PLA) (80%) and polybutylene succinate (PBS) (20%) was prepared first by extrusion, then by injection molding to obtain ...

Shape-memory polymers

open access: yesMaterials Today, 2007
Shape-memory polymers are an emerging class of active polymers that have dual-shape capability. They can change their shape in a predefined way from shape A to shape B when exposed to an appropriate stimulus. While shape B is given by the initial processing step, shape A is determined by applying a process called programming.
