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.
