Mussel‐Inspired Self‐Healing Waterborne Polyurethanes With Catechol–Fe 3+ Coordination and Dynamic Disulfide Bonds
Conventional self‐healing waterborne polyurethanes (WPUs) often suffer from an intrinsic trade‐off between mechanical robustness and healing efficiency. To address this limitation, inspired by the hierarchical structure and dynamic interactions found in marine mussel byssus, a dual dynamic network WPU was synthesiz...
