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

, 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 ...

A torsion test for the study of the large deformation recovery of shape memory polymers [PDF]

, 2011
A torsion device was designed and built for testing the shape fixity and shape recovery of shape memory polymers at large deformation. A simple thermal chamber was used to regulate the thermal environment during testing and a CCD camera was used for ...

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

, 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

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

, 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 ...
