## Description

- description: In this study, ion gels are developed that simultaneously exhibit exceptional
    stiffness and fracture resistance through the synergistic effects of physical
    entanglements and hydrogen bonding between polymer chains within an ionic liquid
    matrix. Through radical copolymerization conducted in an ionic liquid under extremely
    low initiator concentrations, ultrahigh molecular weight polymers in situ with
    nearly complete monomer conversion are successfully synthesized. This strategy
    enabled the one-pot synthesis of physically crosslinked polymer gels composed
    of abundant entanglements and hydrogen bonds between polymer chains. Notably,
    it is demonstrated that the synergy between physical entanglements arising from
    ultrahigh molecular weight polymer chains and noncovalent hydrogen bonding enables
    the simultaneous enhancement of mechanical properties that typically exhibit trade-off
    relationships, such as stiffness, toughness, and fracture resistance. Consequently,
    the synthesized ion gels exhibited outstanding mechanical performances, ranking
    among the best previously reported tough polymer gels, while maintaining a favorable
    balance between ionic conductivity and mechanical strength. These findings underscore
    the broader significance of the approach, indicating that the integration of physical
    entanglements and reversible interactions offers a generalized pathway to mechanically
    robust materials across various polymer systems.
