Shape Memory Effect in Micro-Sized Shape Memory Polymer Composite Chains

open access: yesApplied Sciences, 2019
Since the shape memory effect (SME) has been confirmed in micron and submicron sized polyurethane (PU) shape memory polymer (SMP), it might be used in novel micro/nano devices even for surgery/operation inside a single cell.

On modeling shape memory polymers as elastic two-phase composite materials [PDF]

open access: yes, 2012
A model has been proposed recently, which describes the experimentally observed mechanical behavior of some shape memory polymers. It considers a purely thermoelastic behavior, without strain rate effects, and assumes essentially that the polymer can be ...

High performance shape memory polyurethane synthesized with high molecular weight polyol as the soft segment [PDF]

open access: yes, 2012
Shape memory polyurethanes (SMPUs) are typically synthesized using polyols of low molecular weight (MW~2,000 g/mol) as it is believed that the high density of cross-links in these low molecular weight polyols are essential for high mechanical strength ...
