As witnessed by the presented data charts, the hydrogel's water content is often forgotten but plays an essential role for both the (fracture) mechanical properties and the area of application. Increased water contents generally cause a reduction of stiffness, strength, and fracture energy, while fracture strains can often be enhanced. This effect is largely attributed to the dilution of the network and the neighboring crosslinks, as non-covalent interactions are increasingly weakened (especially in the case of electrostatic interactions). On the microscale, the molecular distribution of water within a given hydrogel seems to be even more consequential, as could be seen in microphase-separated systems. Here, water inhomogeneities systematically promoted modes of energy dissipation, which largely enhanced the mechanical properties. Therefore, we believe that water content on the macro-and the microscale is often underestimated, its intruiging role for energy-dissipating polymer networks is often overlooked and merits more attention. Regarding the area of application, the water content is a vital parameter when considering the biomedical or tissue engineering fields, where within a few mm depth of a single tissue, it may vary vastly (between 20-90%) and tied to it, the (fracture) mechanical properties of the same tissue. Nonetheless, while biomedical applications are often at the very center of attention for many of the highly specialized materials, we should remain receptive to less obvious areas of application including those that reside outside of the traditional hydrogel scope.
