The thermal shape memory behavior of a series of α-amino acid-based poly(ester urea)s has been explored. We demonstrate that these materials exhibit excellent shape memory performance in dual- and triple-shape thermomechanical testing. Significant activation of chain mobility above the as well as a hydrogen bonding network provide the basis for shape transformations and recovery. Additionally, we tuned the shape memory properties of these materials with polymer blending, enabling the demonstration of quadruple-shape memory cycles.
我们已经探究了一系列基于α-氨基酸的聚（酯脲）的热形状记忆行为。我们证明，这些材料在双形状和三形状热机械测试中表现出优异的形状记忆性能。高于玻璃化转变温度时链流动性的显著激活以及氢键网络为形状转变和恢复提供了基础。此外，我们通过聚合物共混来调节这些材料的形状记忆性能，从而实现了四形状记忆循环的演示。
