Rheological analysis of the CHMA-OHA hydrogel. (a) Real-time gelation observation including dynamic crosslinking and photopolymerization. (b) Representative strain sweep with G′ and G″ shows the shear yield of dynamic-hydrogel with increasing strain. (c) Corresponding recovery of dynamic hydrogel undergoing cyclic deformation of 1% and 1,000% strain at 10 rad/s with G′ and G″. (d) Photo of ejecting gels through a 25 G needle without clogging. (e) In situ self-healing macroscopic images of the dynamic CHMA-OHA hydrogel at room temperature.
