Abstract:
The shape memory epoxy polymers (SMEPs) based on the epoxyuretane resin (EPU) modified with poly(ethylene glycol) diglycidyl ether (DEG-1) have been synthesized. Differential scanning calorimetry (DSC) as well as thermomechanical analysis (TMA) have shown that switching temperature (Tsw) can be controlled by variation of EPU/DEG-1 ratio (EPU/DEG-1 ratio was varied from 100/0 to 70/30) in the reactive mixture. According to this Tsw deviation, associated with glass transition temperature Tg, is in the range 114-45 °C. Shape memory characteristics were determined by cyclic TMA. It was found that shape recovery ratio Rr was changed from 72 % to 84 % in the first cycle and was close to 100 % in the following cycles that demonstrated good reproducibility in multiple shape memory cycles deformation/relaxation.
Key words: epoxy polymer, shape memory effect, switching temperature, glass transition temperature, thermomechanical properties.
