This article presents the development of ultralight and superelastic graphene-based cellular monoliths inspired by the hierarchical structure of natural cork. The researchers used a freeze-casting technique to assemble partially reduced graphene oxide (GO) into a structure that mimics the hierarchical organization of cork, resulting in a material that can sustain loads over 50,000 times its own weight and rapidly recover from over 80% compression. The material exhibits exceptional mechanical properties, including high energy absorption, good electrical conductivity, and high efficiency in energy absorption. The unique structure of the monoliths, composed of multiple layers of face-to-face oriented graphene sheets, allows for high elasticity and mechanical robustness. The study highlights the potential of graphene-based materials for applications in flexible electronics, biological tissue scaffolds, and ultralight cellular materials for mechanical damping and thermal/acoustic insulation. The research demonstrates that the combination of graphene chemistry and ice physics can lead to the creation of new materials with remarkable mechanical and electrical properties. The findings suggest that such materials could be used in a wide range of technological applications, including flexible devices and nanocomposites. The study also shows that the mechanical properties of the monoliths can be tuned by adjusting the concentration of GO and the reduction process. The results indicate that the hierarchical structure of the monoliths is crucial for achieving the exceptional mechanical and electrical properties. The study provides a new approach to the synthesis of graphene-based materials with high performance and potential for various applications.This article presents the development of ultralight and superelastic graphene-based cellular monoliths inspired by the hierarchical structure of natural cork.
