A Reversibly Cross‐Linked Network Enables Spider‐Silk‐Like Strain‐Adaptive Mechanical Behavior and Low‐Temperature Tolerance in Artificial Fibers

ABSTRACT Replicating spider‐silk‐like strain‐adaptive mechanical behavior remains challenging because elasticity, rapid stiffening, and energy dissipation must be sequentially activated across distinct deformation regimes. Here, we reproduce this behavior in reversibly cross‐link...

Reversibly Cross‐Linked Damage‐Tolerant Polymers Breaking the Strength–Stretchability Trade‐Off

ABSTRACT Polymers that combine exceptional stretchability with high mechanical robustness are essential for advanced applications. To ensure their reliability, it is critical to integrate damage tolerance, which suppresses crack propagation and prevents catastrophic failure under...
