Shape-memory polymers thermal phase transition

Shape memory polymers basically have two structural features—that is, the cross-links that determine the permanent shape and the reversible segments acting as a switching phase. Molecular mechanisms describing thermally triggered shape memory process are shown in Figure 4.1. In the figure, is the thermal transition temperature of the reversible phase...

A number of reviews of interest have appeared of both a specific and general nature. These include photoresponslve polymers with the main emphasis on phase transitions, memory and shape retention 2 , the kinetics of polyelectrolyte formation , molecular modelling for excimer formation , luminescent probes and molecular dynamics . The uses of thermally stimulated emission for monitoring radical decay and chemiluminescence of polymers...
