Scanning electron microscope image of a Cu–graphene nanopillar with 125-nm layer spacing (a) before and (b) after compression testing. Scale bar, 200 nm. Stress versus strain curves for (c) Ni–graphene and (d) Cu–graphene of various repeat metal layer spacings. The flow stresses at 5% plastic strain versus repeat layer spacing plots for (e) Ni–graphene and (f) Cu–graphene nanolayered composites.
