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.
人工自愈材料的开发是材料科学中一个新兴且具有挑战性的领域。受自然启发——例如贻贝足丝的自愈——金属聚合物作为有吸引力的自愈材料越来越受到关注。这些化合物能够结合聚合物和金属-配体相互作用的特性。开发了一种新型金属聚合物，它由附着的双齿三唑-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有前景的自愈性能。这些材料通过小角X射线散射（SAXS）、紫外-可见光谱和光学显微镜进行表征。
