𝐇𝐨𝐰 𝐜𝐨𝐧𝐝𝐮𝐜𝐭𝐢𝐯𝐞 𝐢𝐬 𝐠𝐫𝐚𝐩𝐡𝐞𝐧𝐞?

The answer depends on what you measure.

A single graphene flake can be highly conductive.

But in real applications, what matters is the conductivity of the film, coating, or network created by millions of flakes.

That depends on more than intrinsic flake conductivity:

→ flake size

→ flake thickness

→ defect density

→ flake-to-flake contact resistance

→ distribution in the final material system

This is why graphene production methods matter.

Graphene oxide can disperse well, but defects reduce conductivity.

Mechanically exfoliated graphene can be conductive, but smaller flakes increase the number of flake-to-flake contacts.

eGraphene is designed differently:

large lateral flakes (~0.5–1 µm), few-layer thickness (<3 nm), and controlled surface functionality — enabling conductive networks with measured bulk conductivities up to 140,000 S/m.

The relevant question is not only:

How conductive is the flake?

But:

How conductive is the network it creates?
