Polymerization of glycinamide-conjugated monomer alone in concentrated aqueous solution enables facile formation of a mechanically strong and a highly stable supramolecular polymer (SP) hydrogel because of the cooperatively hydrogen-bonded crosslinking and strengthening effect from dual amide motifs. This SP hydrogel exhibits thermoplastic processability, injectability, and self-reparability because of the dynamic destruction and reconstruction of hydrogen bonds in response to temperature change.
单独在浓水溶液中聚合甘氨酰胺缀合单体，由于双重酰胺基序的协同氢键交联和增强作用，可轻易形成机械强度高且高度稳定的超分子聚合物（SP）水凝胶。由于氢键在响应温度变化时的动态破坏和重建，这种 SP 水凝胶表现出热塑性加工性、可注射性和自修复性。
