With　the　increasing　demand　in　fields　such　as　wearable　sensors,　soft　robotics,　tissue　engineering,　and　wound　dressings,　the　development　of　hydrogels　with　strong　adhesion　in　wet　environments　has　become　a　critical　focus　of　research.　However,　most　existing　adhesive　materials　lack　the　ability　to　transition　rapidly　and　reversibly　between　the　adhesive　and　nonadhesive　states,　and　their　adhesion　is　often　limited　to　a　single　wet　environment.　In　this　study,　a　smart　interfacial　adhesive　hydrogel　with　tunable　adhesion　properties　across　diverse　liquid　environments　is　presented.　By　tailoring　interchain　interactions　and　leveraging　electrostatically　induced　traction　between　hydrophilic　and　hydrophobic　chain　segments,　the　hydrogel　achieves　reversible　adhesion　modulation　in　response　to　temperature　changes　while　maintaining　strong　wet　adhesion.　Notably,　its　adhesive　strength　at　elevated　temperatures　(45　degrees　C)　is　approximately　three　times　greater　than　at　lower　temperatures　(5　degrees　C).　The　adhesive　hydrogel　exhibits　an　adhesive　strength　of　227　kPa　in　aqueous　environments　and　213　kPa　in　oil-containing　environments.　This　innovative　design　strategy　enables　the　hydrogel　to　exhibit　broad　switchable,　and　dynamic　wet　adhesion　capabilities,　unlocking　significant　potential　for　a　wide　range　of　applications.
