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.

半芳族聚酯到高温形状记忆聚合物的交联，具有完全的回收率

在这项工作中，通过半芳族聚酯聚对苯二甲酸乙二醇酯和聚对苯二甲酸丁二醇酯的端基交联来实现高温形状记忆聚合物。这两个网络均显示出明显高于200°C的触发温度和出色的形状记忆特性，例如200％的可存储应变，所施加应变在临时形状中的完全固定以及永久形状的完全恢复。
