Crosslinking strategies for forming injectable double network hydrogels. (A) Supramolecular and covalently crosslinked hyaluronic acid hydrogels: by increasing the guest−host concentration or the chemical cross-linker concentration, gel modulus is enhanced. (B) Ionically and covalently crosslinked PVA−CPBA hydrogels: by increasing the concentration of Ca²⁺ ions, gel modulus is enhanced. n.d. means no significant difference.
