Key Points

To develop an environmentally tolerant ionogel that balances high damping capacity and mechanical strength through conformation-change mediation and dynamic interfacial coupling.
Incorporated alkenylated cyclodextrin into an ionic liquid matrix using thiol-ene covalent crosslinking, host-guest interactions, and dynamic multi-tiered hydrogen bonding.
Evaluated mechanical, damping, and low-temperature performance, alongside molecular dynamics simulations to elucidate microscopic energy-dissipation pathways.
Achieved a damping capacity greater than 94%, impact strength exceeding 110 MPa, tensile strength of ~7.5 MPa, and toughness of 26.9 MJ/m³.
Maintained environmental stability with a glass transition temperature below −78.8°C and a swelling ratio under 13.7%.
