Hydrogels have attracted much attention due to their intrinsic viscoelastic properties, porous structures, and processability but dehydration of hydrogels often limits the application of these materials. Here, the authors report the distinctive anisotropic dehydration modality of dynamic hydrogels, which is fundamentally different from the more commonly observed isotropic dehydration of covalent hydrogels.
