在本工作中，半芳香族聚酯聚对苯二甲酸乙二醇酯和聚对苯二甲酸丁二醇酯通过端基交联实现了高温形状记忆聚合物。这两种网络都表现出明显高于200°C的触发温度和优异的形状记忆性能，例如200%的可储存应变、所施加的应变在临时形状中完全固定以及永久形状完全恢复。
In this work, high-temperature shape memory polymers are realized by end-group crosslinking of the semiaromatic polyesters polyethylene terephthalate as well as polybutylene terephthalate. Both networks exhibit trigger temperatures distinctly higher than 200 °C and excellent shape memory properties such as storable strains of 200%, full fixity of the applied strain in the temporary shape, and full recovery of the permanent shape.
