Supramolecular Hydrogel Showing Mechanical Robustness and Good Adhesion Underwater.

ABSTRACT: Underwater adhesive materials hold significant application value in fields such as biomedicine and marine engineering. The core performance of these materials lies in the synergistic optimization of their mechanical properties and interfacial adhesive strength. Although supramolecular hydrogels have achieved initial breakthroughs through dynamic bond design, they fail to be mechanically tough and favorably adhesive underwater at the same time. To address this challenge, a strategy to fabricate a supramolecular hydrogel with high crosslinking density using 3D printing technology is proposed. The obtained hydrogel demonstrates excellent mechanical strength due to its high-density hydrogen bonding crosslinks that it retains a tensile stress of 4 MPa and can support a 20 g load without deforma
