Isothermal recovery rates in shape memory polyurethanes

Jan-Anders Edvin Maansson, John Christopher Plummer, Charly David Azra

This work compares the time dependence of isothermal shape recovery in thermoset and thermoplastic shape memory polyurethanes (SMPUs) with comparable glass transition temperatures. In each case, tensile tests have been used to quantify the influence of var ...

Dynamic mechanical analysis for rapid assessment of the time-dependent recovery behavior of shape memory polymers

Jan-Anders Edvin Maansson, John Christopher Plummer, Charly David Azra

Thermally activated shape memory polymers (SMPs) recover from a secondary shape induced by mechanical deformation to a primary equilibrium shape when they are heated to their actuation temperature. In certain applications, for example in the biomedical fie ...

Shape memory polymers with controlled time-dependent shape recovery

Charly David Azra

The aim of this thesis has been to investigate the use of heat-activated shape memory polymers (SMPs) as novel smart actuators for the controlled delivery of fluids and their suitability for applications such as low-cost drug delivery. On heating to temper ...

Influence of molecular architecture on the isothermal time-dependent response of amorphous shape memory polyurethanes

Jan-Anders Edvin Maansson, John Christopher Plummer, Charly David Azra

The thermomechanical response of a series of thermally activated shape memory polyurethanes (SMPUs), determined by dynamic mechanical analysis (DMA), has been adjusted by systematic modification of the molecular architecture. It is argued that the free rec ...
