In this work, it was reported new hydrogel soft material, which can realize the recovery of raw materials and the regeneration of new hydrogels. Conjugated acceptors containing bismethylthiol esters were employed as hydrogel crosslinkers to be substituted by amine derivatives. Four-arm PEG amine was utilized to react with the representative CAs to prepare highly cross-linked polymers. These materials were characterized by their structure, morphology and mechanical properties. These materials can be triggered by ethylenediamine to degrade completely within hours. The original reactant four-arm PEG amine was recovered, and regenerated the hydrogel using the recovered raw material. This innovative recycled polymer demonstrates the potential application of the new material in terms of manufacturing cost savings and material sustainability.
