Compressibility of 3D-graphene, 3D-graphene/Pt and 3D-graphene/Ag naocomposites.
(a–c) Digital images of a typical compression process of 3D-graphene/noble metal nanocomposites. Compressive stress-strain curves of 10 cycles (loading and unloading) of (d) 3D-graphene/Pt and (e) 3D-graphene/Ag nanocomposites (Inset: Compressive stress–strain curve of 3D-graphene).
