Soft and flexible conductive materials are considerable interest as mobile power supplies for future electronics, including soft robotics, wearable devices, and electronic skins. In this regard, graphene hydrogels are considered promising flexible composite materials because they can exhibit excellent electrical conductivity, flexibility, and mechanical robustness. However, investigating conductive materials that fulfill the advanced applications remains a challenge. Here, we newly fabricated physically cross-linked graphene hydrogels through cation-π interaction with zwitterionic imidazolium-based polymers. We established facile and novel synthetic methods for fabricating graphene hydrogels by using microwave irradiation which induces exfoliation of graphite and polymerization simultaneously. In this presentation, extremely simple method to fabricating graphene hydrogels and their electrochemical performances, adhesive, reusable, and robustness properties will be discussed.
