摘要

Supramolecular ionogels constructed based on the synergistic interactions of hydrogen bonding and ion-dipole interactions are able to simultaneously achieve mechanical strength

self-recovery

environmental tolerance

and impact resistance

which exhibiting significant potential for applications in wearable devices and electronic components protection.

Abstract

Supramolecular materials that combine toughness

transparency

self-healing

and environmental stability are crucial for advanced applications

such as flexible electronics

wearable devices

and protective coatings. However

integrating these properties into a single system remains challenging because of the inherent trade-offs between the mechanical strength

elasticity

and structural reconfigurability. Herein

we report a supramolecular

ionogel designed

via

a simple one-step polymerization strategy that combines hydrogen bonding and ion-dipole interactions in a physically crosslinked network. This dual-interaction architecture enables the ionogel to achieve high tensile strength (9 MPa)

remarkable fracture toughness (23.6 MJ·m

−3

)

and rapid self-healing under mild thermal stimulation. The material remains highly transparent and demonstrates excellent resistance to moisture

acid

and salt environments

with minimal swelling and performance degradation. Furthermore

it effectively dissipates over 80 MJ·m

−3

of energy during high-speed impacts

providing reliable protection to fragile substrates. This study offers a broadly applicable molecular design framework for resilient and adaptive soft materials.
