Deep eutectic solvent based adhesive with dynamic adhesion, water-resistant and NIR-responsive retrieval properties

Adhesives that exhibited dynamic adhesion in underwater environments are of great importance. Here, we report a simple yet versatile method to fabricate underwater adhesive with time-dependent dynamic adhesion derived from the silane-based polymerized deep eutectic solvent (PDES). Particularly, the incorporation of silane can endow the underwater adhesive with a time-dependent adhesive performance, i.e., the adhesion strength increased at first and then decreased. With the further introduction of MXene, NIR-controlled retrieval property can be achieved. We anticipate that the alternative strategy presented here will open a new avenue for designing high-performance underwater adhesive materials with tunable and synergistic properties.

Automated summary

We report a simple yet versatile method to fabricate underwater adhesive with time-dependent dynamic adhesion derived from silane-based polymerized deep eutectic solvent (PDES). The adhesive exhibits dynamic adhesion in underwater environments and can be tuned for optimal performance. The introduction of MXene enables near-infrared (NIR)-controlled retrieval property. This alternative strategy opens up new possibilities for designing high-performance underwater adhesive materials.
