The IPN hydrogels have been widely investigated as promising materials to the poor mechanical properties of existing hydrogels. The catechol-containing molecules as a crosslinking mediator can physically interact through π-π stacking, cation-π interaction, and hydrogen bonding. In this work, bio-inspired adhesive double network hydrogels were prepared by the polyacrylamide(PAAm), mussel inspired copolymers and various cation(Ca2+, Fe3+, V5+) to induce the formation of catechol-metal coordination interaction. The prepared IPN-structured hydrogels were evaluated to mechanical properties and characterized. It could be used for the studying the interaction of metal cations with a mussel-inspired copolymers/PAAm IPN hydrogel for biomaterials field. |
