Strong, Compressible, and Ultrafast Self‐Recovery Organogel with In Situ Electrical Conductivity Improvement

Coordination complexes are widely used to tune the mechanical behaviors of polymer materials, including tensile strength, stretchability, self-healing, and toughness. However, integrating multivalent functions into one material system via solely coordination is challenging, even using combinations metal ions ligands. Herein, a single-step process described silver-based as cross-linkers enable high compressibility (>85%). The resultant organogel displays compressive strength (>1 MPa) with low energy loss coefficient (<0.1 at 50% strain). Remarkably, it demonstrates an instant self-recovery room temperature speed >1200 mm s−1, potentially being utilized for designing high-frequency-responsive soft materials (>100 Hz). Importantly, in situ silver nanoparticles formed, effectively endowing conductivity (550 S cm−1). Given synthetic simplification achieve multi-valued properties single metal-based complexes, such organogels hold significant potential wearable electronics, tissue-device interfaces, robot applications.
