Flexible supercapacitors are considerable interest as mobile power supply for future flexible electronics. In this regard, graphene hydrogels are considered promising flexible supercapacitors because they can exhibit both excellent electrical conductivity, flexibility and mechanical robustness. Here, we newly fabricated physically cross linked graphene hydrogels via cation-π interaction with zwitterionic imidazolium based polymers. We established facile and novel synthetic methods for fabricating cation-π interacted graphene hydrogels by using microwave irradiation which induces exfoliation of graphite and polymerization simultaneously. In this presentation, facile method to fabricating graphene hydrogels and their electrochemical performances will be discussed. |
