## Description

- description: 'We report a facile one-step synthesis of homogeneous polymer network
    ion gels (ionogels). The gelation process was based on the cross-linking of tetra-branched
    poly(ethylene glycol) (TetraPEG) with a chelate ligand via metal ion complexation
    in ionic liquid–based solutions containing Ni2+, Mg2+, and Li+. Specifically,
    the end-functionalization of TetraPEG with catecholamine (containing a catechol
    (Cat) group) and the formation of complexes between the metal ions and the Cat
    group proceeded simultaneously to yield free-standing TetraPEG ion gels. We investigated
    the mechanical properties of the ion gels via mechanical stress tests to determine
    the effect of the utilized metal ions (in the IL solutions) on the mechanical
    properties of the TetraPEG–Cat ion gels. The mechanical strength of the ion gels
    strongly depended on the coordination bond strengths of the metal ions in the
    metal–Cat complexes, displaying the following trend: Ni2+ > Mg2+ > Li+. Furthermore,
    as a first step toward achieving the application of the ion gels as gel electrolytes
    in electrochemical devices, we measured their ionic conductivities and found that
    the TetraPEG–Cat ion gels exhibited high ionic conductivity regardless of the
    employed metal ion species.'
