Salt-welding strategy for the design of repairable impact-resistant and wear-resistant hydrogels.

Generally, both G ′ and G ′′ showed an increasing trend as the anion switching from “salting-in” to “salting-out.” As shown in Fig. 2H , the G ′ and G ′′ data overlapped well on master curves, with the PMHB hydrogel as the reference state, the relative swelling ratio of the hydrogel ( Q v ; fig.
