The development of hydrogel materials with enhanced mechanical properties is the primary focus in designing autonomous self-healable hydrogel materials. Here, we present a facile and cost-effective method for the autonomous self-healing hydrogel based on Glycogen (Gly/PAA-Fe) with enhanced mechanical properties by simple insertion of ferric ions in the physically cross-linked network via metal-ligand interactions. This dual physically cross-linked hydrogel has an excellent elongation at break and self-healing properties due to the dynamic ionic cross-linking point. This work will encourage researchers to focus on this facile technique for the synthesis of self-healing hydrogel materials with enhanced mechanical properties.
增强机械性能的水凝胶材料的开发是设计自主自修复水凝胶材料的主要关注点。在这里，我们提出了一种简单且经济有效的方法，通过金属配体相互作用将铁离子简单地插入物理交联网络中，在 Glycogen（Gly/PAA-Fe）上制备具有增强机械性能的自主自修复水凝胶。由于动态离子交联点，这种双重物理交联水凝胶具有出色的断裂伸长率和自修复性能。这项工作将鼓励研究人员关注这种简便的技术，用于合成具有增强机械性能的自修复水凝胶材料。
