Abstract:Shape memory epoxy resin of PU/ TDE-85 was prepared by using tetrahydromethyl-1,3-isobenzofurandione(
METHPA) as a curing agent. The characteristics of the blends were investigated by tensile test, SEM,
DMA and FTIR. Blends with varying proportions of PU/ TDE-85 were studied for their mechanical properties, thermodynamics,
glass-transition temperature and shape memory properties. The test results show that the toughness of epoxy
resin was improved by adding PU. And the glass-transition temperature also decreased accordingly. Moreover, the
material exhibited a good shape memory performance, the shape recovery and the shape fixity of this material can achieve
96% and 100%, respectively
