Chemically triggered life control of"smart"hydrogels through click and declick reactions
文献摘要：
The degradation of polymeric materials is reco-gnized as one of the goals to be fulfilled for the sustainable economy.In this study,a novel methodology was pre-sented to synthesize multiple highly cross-linked polymers(i.e.,hydrogels)through amine-thiol scrambling under mild conditions.Amine-terminated poly(ethylene glycol)(PEG-NH2)was reacted with the representative conjugate accep-tors to synthesize hydrogels in organic and aqueous solu-tions,respectively.The materials above exhibited high water-swelling properties,distributed porous structures,as well as prominent mechanical strengths.It is noteworthy that the mentioned hydrogels could be degraded efficiently in hours to release the original coupling partner,which were induced by ethylene diamine at ambient temperature through amine-amine metathesis.The recovered PEG-NH2 reagent could be employed again to regenerate hydrogels.Due to the multiple architectures and functions in poly-meric synthesis,degradation and regeneration,a new generation of"smart"materials is revealed.
