由于双酰胺基序的协同氢键交联和增强作用，在浓水溶液中单独聚合甘氨酰胺共轭单体可以轻松形成机械强度高且高度稳定的超分子聚合物（SP）水凝胶。由于氢键响应温度变化的动态破坏和重建，这种 SP 水凝胶表现出热塑性加工性、可注射性和自修复性。
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.
