人工自修复材料的发展代表了材料科学中一个新兴且具有挑战性的领域。受自然界的启发，例如贻贝足丝的自愈性，金属聚合物作为一种有吸引力的自愈性材料越来越受到人们的关注。这些化合物能够联合收割机结合聚合物和金属-配体相互作用的性质。开发了一种新型的金属聚合物，由连接的双齿三唑-吡啶（TRZ-py）配体和低玻璃化转变温度（Tg）的甲基丙烯酸月桂酯主链组成。该聚合物与不同的Fe（II）和Co（II）盐交联。所得材料在50至100 °C的中等温度下在5.5至26.5小时的时间间隔内表现出良好的自愈合性能。材料的特征在于X射线散射（SAXS），紫外-可见光谱，和光学显微镜。
The development of artificial self-healing materials represents an emerging and challenging field in material science. Inspired by nature-for instance by the self-healing of mussel byssus threads-metallopolymers gain more and more attention as attractive self-healing materials. These compounds are able to combine the properties of both polymers and metal-ligand interactions. A novel metallopolymer is developed consisting of attached bidentate triazole-pyridine (TRZ-py) ligands and a low glass transition temperature (T g ) lauryl methacrylate backbone. The polymer is cross-linked with different Fe(II) and Co(II) salts. The resulting materials exhibit promising self-healing performance within time intervals of 5.5 to 26.5 h at moderate temperatures of 50 to 100 °C. The materials are characterized by X-ray scattering (SAXS), UV-Vis spectroscopy, and light microscopy.
