Structural and mechanical properties of the L‐DPZ hydrogels. A) Schematic illustration of the synthesis of the L‐DPZ hydrogels. B) SEM images of the surface and cross‐section of the L‐DP hydrogel. SEM and EDS images of the C) L‐DPZ1 and D) L‐DPZ2 hydrogels. E) FTIR spectra of the L‐DP, L‐DPZ1, and L‐DPZ2 hydrogels. F) C1s and G) O1s high‐resolution XPS spectra of the L‐DP, L‐DPZ1, and L‐DPZ2 hydrogels, respectively. H) Photographic image showing the injectability of the L‐DPZ2 hydrogel, wherein a blue dye was used to stain the hydrogel sample for visibility purposes. I) Photographic images demonstrating the self‐healing behavior of the L‐DPZ hydrogel. J) Variation in the storage modulus (G′) and the loss modulus (G′′) of the L‐DPZ2 hydrogel, as determined using the strain amplitude sweep test (0.01–1000%). K) Variation in the viscosity of the L‐DPZ2 hydrogel, as determined using the shear‐thinning test. L) Variations in G′ and G′′ for the L‐DPZ2 hydrogel, as observed during three alternate step‐strain tests.
