Abstract—Shape memory polyurethane is attractive in recent years because of its wide applications in many fields. In order to study the moisture-sensitive shape memory effect of pyridine containing shape memory polyurethane, in this work, moisture absorption and moisture-sensitive shape memory behavior of pyridine containing SMPU synthesized from BINA and IPDI are investigated systematically. The results show that IPDI-BINA SMPU shows moisture absorption and the moisture absorption affects significantly the thermal and DMA properties. Finally, shape recovery process under moisture condition demonstrates that IPDI-BINA SMPU show moisture-sensitive shape memory effect that it can recover the origin shape under the moistures condition.

Index Terms—Shape memory, polyurethane, moisture sensitive, diisocyanates.
