Abstract Mechanically robust and tough polymeric materials are in high demand for applications ranging from flexible electronics to aerospace. However, achieving both toughness strength polymers remains a significant challenge due their inherently contradictory nature. Here, universal strategy enhancing the of polymer blends using ligand‐modulated metal–organic framework (MOF) nanoparticles is presented, which engineered have adjustable hydrophilicity lipophilicity by varying types ratios ligands. Molecular dynamics (MD) simulations demonstrate that these can effectively regulate interfaces between chemically distinct based on amphiphilicity. Remarkably, mere 0.1 wt.% MOF with optimized amphiphilicity (ML‐MOF (5:5) ) delivered ≈1.1‐ ≈34.1‐fold increase poly (lactic acid) (PLA)/poly (butylene succinate) (PBS) blend, respectively. Moreover, amphiphilicity‐tailorable universally enhance mechanical properties various blends, such as polypropylene (PP)/polyethylene (PE), PP/polystyrene (PS), PLA/poly adipate‐co‐terephthalate) (PBAT), PLA/polycaprolactone (PCL)/PBS. This simple method offers potential strengthening toughening blends.

Abstract The rapid advancement in attractive platforms such as biomedicine and human‐machine interaction has generated urgent demands for intelligent materials with high strength, flexibility, self‐healing capabilities. However, existing ability are challenged by a trade‐off between low elastic modulus, healing due to the inherent strength of noncovalent bonding. Here, drawing inspiration from human fibroblasts, monomer trapping synthesis strategy is presented based on dissociation reconfiguration amphiphilic ionic restrictors (7000‐times volume trapping) develop eutectogel. Benefiting nanoconfinement dynamic interfacial interactions, molecular chain backbone formed confined domains mechanically reinforced while preserving soft movement resulting eutectogels demonstrate superior mechanical properties (1799% 2753% higher tensile toughness than pure polymerized deep eutectic solvent), excellent efficiency (>90%), tangential modulus (0.367 MPa during working stage), sensitively monitor activities. This poised offer new perspective developing wearable electronics tailored body motion.
