(a) Schematic illustration of the fabrication of carbon–graphene (C–G) monolith. (b) SEM image (top view) of C–G monolith shows the lamellar multi-arch microstructure with long-range alignment. Scale bar, 100 μm. (c) High resolution transmission electron microscopy image shows that the lamella is composed of amorphous carbon and graphene composite. Scale bar, 2 nm. (d) Stress–strain curves of C–G monolith under high strain compression. (e) Real-time images from high-speed camera showing that C–G monolith can rebound a steel ball at large speed, in a springlike fashion. Scale bar, 4 mm. (f,g) Recovery speed (f) and energy loss coefficient (g) of C–G monolith and other previously reported materials. Numbers in the charts represent relevant references.
