Shape memory effect materials

Polymers exhibiting a shape-memory effect have both a visible, current (temporary) form and a stored (permanent) form. Once the latter has been manufactured by conventional methods, the material is changed into another, temporary form by processing through heating, deformation, and finally, cooling. The polymer maintains this temporary shape until the shape change into the p… WebbThe SMMD tool provides one-stop access to an extensive collection of shape memory materials information in a single source.
