A fast-healing and high-performance metallosupramolecular elastomer based on pyridine–Cu coordination

This study is led by Dr. Jinrong Wu (State Key Laboratory of Polymer Materials Engineering, College of Polymer Science and Engineering, Sichuan University). In high-speed devices, cracks propagate very quickly and brings irreversible destruction. However, materials that can self-heal quickly often have poor performance. In many applications, once a crack appears, a catastrophic accident may occur if it is not repaired in time. Therefore, it is extremely important to develop fast self-healing materials without compromising their mechanical properties.
