Xie et. al. has created a shape memory material that contains multiple “temporary shape” through creating a layered polymer material. This material was created by layering two polymers with different glass transition temperatures. The first layer was made from a mole ratio of 1.6 mole Epon 826/0.4 mole NGDE/1 mole Jeffamine. It was placed in the mold and cured at 100 deg C for 40 minutes. The second layer was made from a mole ratio of 0.8 mole Epon 826/1.2 mole NGDE/1 mole Jeffamine. This mixture was poured on top of the first layer and cured for an additional 40 minutes at 100 deg C. Then the mold was post-cured at 130 deg C for 1 hour. The first layer had a Tg of approximately 48 deg C and the second layer had a Tg of approximately 75 deg C. The figure below shows the shape setting and recovery process.
