“…Given its long-term stability and strong adhesion strength, the adhesive is well-suitable for long-term use (Figure 5h). Figure 5i and Table S1 (Supporting Information) have summarized the highest underwater adhesion strength of recently reported underwater adhesives (named as SF-BGE/TA, [5] Poly(TA-PA)s, [7] BACT gel, [4] AFBA, [9] Glycerol-Based Algae-Mussel Glue, [48] P(ECO-co-AAc-co-TAc), [8] Poly(catechol-styrene), [49] VATA, [50] Fe-PAM-C-M, [51] HBP, [2] HDI-PDMS, [18] Ionogel, [52] PVA exogels, [53] SiW-P123, [6] BSA, [54] UPGAs, [55] PEDA, [3] the rSer-TA, [1] supramolecular P1 [56] ). In comparison, the adhesive developed in this work exhibits tough underwater adhesion with a highest underwater adhesion strength of 5.478 ± 0.654 MPa, which is superior to most underwater adhesives.…”

Developing tunable underwater adhesives that possess tough adhesion in service and easy detachment when required remains challenging. Herein, a strategy is proposed to design a near infrared (NIR) photothermal‐responsive underwater adhesive by incorporating MXene (Ti3C2Tx)‐based nanoparticles within isocyanate‐modified polydimethylsiloxane (PDMS) polymer chains. The developed adhesive exhibits long‐term and tough adhesion with an underwater adhesion strength reaching 5.478 MPa. Such strong adhesion is mainly attributed to the covalent bonds and hydrogen bonds at the adhesive‐substrate interface. By making use of the photothermal‐response of MXene‐based nanoparticles and the thermal response of PDMS‐based chains, the adhesive possesses photothermal‐responsive performance, exhibiting sharply diminished adhesion under NIR irradiation. Such NIR‐triggered tunable adhesion allows for easy and active detachment of the adhesive when needed. Moreover, the underwater adhesive exhibits photothermal antibacterial property, making it highly desirable for underwater applications. This work enhances the understanding of photothermal‐responsive underwater adhesion, enabling the design of tunable underwater adhesives for biomedical and engineering applications.

Barnacles convert hydrophilic proteins into an insoluble, yet aqueous, material that functions as a permanent underwater adhesive. Here, it is demonstrated that a common hydrophilic protein, bovine serum albumin, can be chemically triggered underwater to aggregate into a similar aqueous adhesive that mimics the formation of the natural adhesive. The combined action of multiple chemical denaturants initiates rapid gelation followed by further curing over time in artificial seawater. The adhesive strengths of this waterborne adhesive measured by lap shear are comparable to many bioinspired adhesives that use organic solvents and a high fraction of hydrophobic components. This approach establishes a bioinspired adhesive that can be deployed at practical scales in marine environments, produced sustainably, and sourced from low‐cost materials.
