Abstract As technology has developed by leaps and bounds over decades, the development of high‐performance supramolecular adhesives become crucial in both scientific industrial fields. Ionic liquids (ILs)‐based adhesives, containing ILs segment, utilizing chemical structure as either primary adhesive component or key functional group, have materialized a highly transformative subject matter for cutting‐edge emerging applications. Rational design strategies, carefully balancing adhesion cohesion behavior, are also required when constructing ILs‐based adhesives. Herein, detailed discussion on latest advancements is provided design, including strategies such IL monomer decoration/polymerization creation ionogels, etc. Leveraging abundant toolbox obtained rich (macro)molecular configuration, these can address general specific requirements, offering distinctive advantages great potential practical From this perspective, it outlines summarizes recent research rational manufacturing technique toward advanced sensory, underwater, electric‐controlled biomedical applications, particularly proposing guidance construction tailor‐made glues.

Abstract Epoxy resins, widely recognized for their stable cross‐linked structures and extensive use as adhesives, face a fundamental challenge in balancing high‐performance attributes with dynamic functionalities. To address this, novel strategy leveraging synergistic effects is proposed to amplify bonds within the resin network. Specifically, an ionic monomer featuring imidazole cations benzene rings synthesized combined four‐arm thiol‐containing ester groups, forming network through dual curing process. This design endows thermoset multiple stimuli‐responsive The groups are pivotal enabling resin's degradability reprocessability, while non‐covalent cation‐π interactions significantly enhance energy dissipation, resulting superior mechanical properties. Notably, not only lower barrier of epoxy thermal reaction but also accelerate hydrolysis via hydrogen bonding. work demonstrates tunable responsive adhesive cyclic features, offering promising candidate functional applications devices beyond. innovative integration provides versatile platform designing next‐generation resins both high performance full life‐cycle sustainability.
