Abstract Conventional adhesives generally suffer from diminished adhesion in aqueous environments, posing significant challenges for their application wet and submerged conditions. While extensive research efforts are directed toward enhancing the interfacial bonding, cohesive strength, durability of such most existing underwater remain static irreversible. This limitation hinders reusability often results undesirable residues. Addressing challenge achieving strong with on‐demand detachment remains crucial. study introduces development temperature‐responsive that demonstrate outstanding bonding reversibility, durability. Through strategic integration reinforced cross‐linking networks, dynamic hydrogen bonds, upper critical solution temperature (UCST)‐driven phase transitions, one few temperature‐deactivated is created. The optimized adhesive distinguished by its performance to achieve strengths exceeding 1.4 MPa, nearly 100% switching efficiency residue‐free adherend under mild thermal cycling. Beyond template‐assisted fabrication patches, 3D printable achieved programmable architectures via direct ink‐writing. work highlights activated UCST‐type not only boosting efficiencies across various water conditions but also broadening applicability user‐defined application‐specific functions.
