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

Mechanical and Shape Memory Properties of Poly(vinyl acetate)/Poly(lactic acid) Blends [PDF]
Hypothesis: Shape memory polymers (SMPs) are intelligent materials that can be set into temporary shape and return to their permanent (original) shape when an external stimulus is applied. Poly(vinyl acetate) (PVAc) is a low cost biopolymer. However, its

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.

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

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

Thiol‐ene Reaction as Reversible Covalent Bond for the Design of Shape‐Memory Polymers
Besides a stable phase, shape‐memory polymers require an additional switchable moiety. In addition to thermal transitions and supramolecular interactions, these units can also be based on covalent bonds.

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