Hydrogen bond-triggered self-healing polyurea elastomers with mechanical robustness via dual-dynamic phase structure construction

Key Points

• The aim is to develop a polyurea elastomer that combines self-healing properties with mechanical strength.
• Fabrication of polyurea elastomers with dual dynamic structures
• Implementation of a multi-hydrogen bond system
• The elastomers achieved a balance between mechanical robustness and self-healing capabilities
• Enhanced performance was observed due to the dual-dynamic phase structure
