Mechanical properties of the Fe-TA@P(AM-AA) hydrogel. (A) Viscoelastic behavior of Fe-TA@P(AM-AA) hydrogels. (B) Tensile stress–strain curves of Fe-TA@P(AM-AA) hydrogels. (C) Compression stress–strain curves of Fe-TA@P(AM-AA) hydrogels. (D) Model of loading–unloading compression tests of Fe-TA@P(AM-AA) hydrogels. (E) Successive loading–unloading cycling compression tests of the Fe-TA@P(AM-AA) hydrogel, conducted three times at each of the strain ratios: 30, 50, and 70%. (F) Strain amplitude scan test of Fe-TA@P(AM-AA) hydrogels. (G) Continuous alternating strain scan of Fe-TA@P(AM-AA) hydrogels. (H) Images of self-healing properties of Fe-TA@P(AM-AA) hydrogels.
