A free-standing ion-conductive gel is formed by spontaneous self-assembly of the amphiphilic ionic liquids and the cross-linkable monomer 6-hexanediol diacrylate (HDODA) in a mixed solvent of 1-octene, 1-butanol, and water. The ionic conductivity of this ion gel is 24 mS cm−1 at 33 °C. To enhance the mechanical strength of the ion gels, an acrylate ionic liquid was added, leading to significant morphological changes of the HDODA phase from spherical, ellipsoid, angular platelets to interconnected with increasing addition of an acrylate ionic liquid and consequent enhancement in the mechanical strength of the resulting ion gels. SAXS data reveal that the ion gels are composed of bicontinuous phase. The formation of the anisotropic HDODA structures upon introduction of the acrylate ionic liquid was accompanied by a change of the bicontinuous phase to be undulated, which increased the ionic path through the formed film, resulting in reduced ionic conductivity. |
