Hydrogels comprising acylhydrazone and micellar crosslinks [99]. (a) Synthetic strategy: Homotelechelic aldehyde functionalized triblock co-polymers are crosslinked at a pH = 6 with a three-arm acylhydrazine. (b) Uniaxial tensile test of the dual dynamic hydrogel and a hydrogel comprising solely acylhydrazone crosslinks. (c) Uniaxial tensile tests of the dual network at different pH values. The gel shows the highest stability at pH = 6.0. Reprinted (adapted) with permission from Reference [99]. Copyright (2017) American Chemical Society.
