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 ...

Light activated shape memory polymers and composites: A review

, 2020
Shape memory polymers and their composites are capable to hold a temporary shape and recover to the original shape upon exposure to a particular external stimulus. The stimulus light is considered as the optical radiation of any wavelength from 1 to 10^6

A molecular dynamics investigation of the deformation mechanism and shape memory effect of epoxy shape memory polymers [PDF]

, 2016
Following deformation, thermally induced shape memory polymers (SMPs) have the ability to recover their original shape with a change in temperature. In this work, the thermomechanical properties and shape memory behaviors of three types of epoxy SMPs ...

A Supramolecular Polymer Formed by Small Molecules

Cell Reports Physical Science, 2020
Summary: Supramolecular polymers are intriguing due to their thermal reversible and stimuli-responsive properties. However, most supramolecular polymers reported thus far have poor mechanical properties due to the low bonding energy of the non-covalent ...
