Abstract

A reversible triple-shape effect is achieved for multi-phase polymer networks based on two different crystallizable segments. The reversibility of the two shape-changes is based on crystallization induced elongation (CIE) occurring during cooling and melting-induced contraction (MIC) during heating under constant stress.
