Abstract The resistance of adhesives to organic solvents is paramount importance in diverse industries. Unfortunately, many currently available exhibit either weak intermolecular chain interactions, resulting insufficient solvents, or possess a permanent covalent crosslinked network, impeding recyclability. This study introduces an innovative approach address this challenge by formulating zwitterionic poly(ionic liquid) (ZPIL) derivatives with robust dipole–dipole incorporating sulfonic anions and imidazolium cations. Due its unique dynamic electrostatic self‐crosslinking structure, the ZPIL exhibits significant adhesion various substrates demonstrates excellent recyclability even after multiple tests. Significantly, exceptional stability across nonpolar polar including ionic liquids, distinguishing itself from nonionic polymers conventional liquid)s. Its adhesive performance remains minimally affected prolonged exposure soaking conditions. presents promising solution for design highly solvent‐resistant materials plastics, coatings, adhesives.

Abstract Zwitterionic hydrogels with exceptional antifouling properties and biocompatibility have gained widespread attention in biomedical applications. However, achieving robust mechanical performance while maintaining high water content within a single‐network zwitterionic hydrogel remains challenging.
