Abstract: Ion conduction through graphene oxide (GO) nanosheets that is pH-switchable between H <superscript>+</superscript> (in acid) and OH <superscript>-</superscript> (in base) ions is demonstrated. This finding is the first observation of this type for ion conductive materials and demonstrates an example of stimuli-driven ion-conduction switching.
