Shape-memory polymers (SMP) are a unique branch of the smart materials family which are capable of changing shape on-demand upon exposure to external stimulus.

The basic principles and mechanism of shape memory polymers, classification of shape memory polymers, and related characterization techniques are illustrated. F

Polyurethanes are formed by reacting a polyol (an alcohol with more than two reactive hydroxyl groups per molecule) with a diisocyanate or a polymeric isocyanat
