A Uniaxial Mechanochemical Coupling Model for Chemical Bond Scission-Triggered Self-Strengthening in Double-Network Hydrogels

Key Points

• Self-strengthening occurs through chemical bond scission triggered by uniaxial stress in hydrogels.
• Key finding shows increased material resilience with tensile stress, enhancing performance tenfold under certain conditions.
• Observational analysis using a mechanochemical coupling model to explore bond breakage mechanisms in double-network systems.
• This research suggests practical applications in developing stronger hydrogels, needing further verification in real-world scenarios.
