In this contribution, a series of adamantane (AD)-containing polyurethanes were prepared from 1,3-adamantanediol, 1,4-butanediol and hexamethylene diisocyanate, and the influences of AD on the shape memory behavior of polyurethanes were systematically studied. Due to large steric hindrance, AD was able to disrupt the regular arrangement of polyurethane chains and contributed to forming an amorphous domain. It was found that moderate AD-containing polyurethanes had good mechanical properties and broad glass transition, and shape memory tests confirmed these polyurethanes possessed a shape fixation rate of 98% and shape recovery rate of 91% during a dual-shape memory procedure. Furthermore, they also exhibited a triple-shape memory effect. This work demonstrated a facile and feasible way to prepare polyurethane-based shape memory materials by using adamantane as a functional unit.

基于含金刚烷聚氨酯的形状记忆材料†
在这项贡献中，由 1,3-金刚烷二醇、1,4-丁二醇和六亚甲基二异氰酸酯制备了一系列含金刚烷 (AD) 的聚氨酯，并系统地研究了 AD 对聚氨酯形状记忆行为的影响。由于较大的空间位阻，AD 能够破坏聚氨酯链的规则排列并有助于形成无定形域。研究发现，中等含量的含有 AD 的聚氨酯具有良好的机械性能和广泛的玻璃化转变，形状记忆测试证实这些聚氨酯在双形状记忆过程中具有 98% 的形状固定率和 91% 的形状恢复率。此外，它们还表现出三重形状记忆效应。
