Nanoscale Size Reference

Graphene oxide (flake diameter 1.5–5.5 µm, thickness 0.43–1.23 nm) is graded by flake diameter and layer thickness, not by US mesh/sieve number — a flake this thin passes through any sieve regardless of its diameter. Flake diameter and thickness are specified directly in microns/nanometers, as in the table above. For reference, here is how nanometers relate to microns and millimetres:
