Effect of Chemical Composition on the Deformability of Shape-Memory Epoxies

Newly developed shape memory (SM) epoxies are unveiled with an improved deformability range, high strength with intrinsically good thermal and chemical stability, high thermal transition (i.e., SM transformation temperature), and qualitatively excellent SM characteristics, thereby providing a synthetic route for adding attractive properties to commonly used industrial and commodity resins. The impact of chemical composition on the failure strains of these SM epoxies is shown and the resulting SM behavior is discussed.
