Abstract Underwater adhesives receive extensive attention due to their wide applications in marine explorations and various related industries. However, current still suffer from excessive water absorption lack of spontaneity. Herein, we report an autonomous underwater adhesive based on poly(2-hydroxyethyl methacrylate- co -benzyl methacrylate) amphiphilic polymeric matrix swollen by hydrophobic imidazolium ionic liquid. The as-prepared is tough flexible, showing little none instantaneous adhesion onto the PET substrate, whereas its energy substrate can grow more than 5 times 458 J·m −2 after 24 hours. More importantly, this process entirely spontaneous, without any external pressing force. Our comprehensive studies experimental characterizations molecular dynamic simulations confirm that such driven water-induced rearrangement functional groups. It believed material provide insights into development next-generation smart adhesives.
