Data availability statement

In addition to this hydrophobic elastomer, Yu and Wu developed a hydrophobic ionic liquid gel by using a water-insoluble anion (Fig. 4b) [ 54]. In their strategy, they first prepared two ionic liquids with the same hydrophobic anion, one being butyltrimethylammonium bis(trifluoromethanesulfonyl) imide ([N4111][TFSI]), working as solvent, the other one being [2-(methacryloyloxy)ethyl]trimethylammonium bis(trifluoromethanesulfonyl) imide ([MATAC][TFSI]) monomer. After one-pot polymerization, a viscoelastic ionogel was fabricated. The ionogel did not swell in water due to its hydrophobicity and exhibited various properties, including optical transparency, tunable mechanical properties, self-healing ability, underwater adhesiveness, conductivity, and 3D printability.

This unique property of hydrogels lays the foundation for their application in underwater adhesion. However, due to the existence of the hydration layer, the interaction between the hydrogel and the adherend surface is seriously hindered, and the underwater adhesion ability of the hydrogel is severely weakened. In the past few decades, various hydrogels for underwater adhesion have been developed, among which the underwater adhesion mechanisms of natural organisms have provided a steady stream of inspiration for researchers to design underwater adhesion hydrogels. In this review, we first summarize the adhesion mechanism and design strategies of underwater adhesion hydrogels, and then introduce the currently common experimental methods to test the adhesion strength and adhesion toughness of underwater adhesion hydrogels. According to the development trend in recent years, we summarize the common application fields of underwater adhesion hydrogels. Finally, we present our views on the challenges of hydrogels for underwater adhesion, and provide an outlook on future research directions. This review provides a comprehensive overview of underwater adhesion hydrogels, which will provide rational guidelines for the design and fabrication of underwater adhesion hydrogels. C. Wei, X.
