The 3D-bonded spongy graphene material exhibits super compressive elasticity and near-zero Poisson’s ratio. They function as enthalpic rubbers, which can recover up to 98% compression in air and 90% in liquids, and operate between −196 and 900 °C. Furthermore, they provide reversible liquid absorption for hundreds of cycles and then discharge it within seconds, while still providing an effective near-zero Poisson’s ratio.
