Figure 4

Stress–strain curves during loading–unloading cycles in sequence of increasing strain amplitude for (a) bulk graphene aerogel (31 mg cm−3) and (b) 3D printed graphene aerogel microlattice (16 mg cm−3) using the GO ink without R–F, (c) bulk graphene aerogel (123 mg cm−3) and (d) 3D printed graphene aerogel microlattice (53 mg cm−3) using the GO ink with R–F.
