Frustration-mediated structural-state selection tunes ionic conductivity in confined polymer--ionic liquid materials

This study demonstrates that in confined polymer–ionic liquid materials, competing ordering tendencies can be resolved through frustration-mediated structural-state selection, where the suppression of long-range order into a predominantly amorphous state (as seen in pMBA–FSI) uniquely optimizes ionic conductivity by overcoming the traditional trade-off between structural order and molecular mobility.
