: The "Ferrari" of the group. A single sheet of graphene. Best for high-end electronics and sensors.

: Multi-walled nanotubes are available in bulk (ton quantities) for industrial integration. 3. Select a Trusted Manufacturer

: Arc-discharge SWCNTs can cost between $75 and $300 per gram depending on purity and length.

: The "workhorse." Multiple nested tubes. Ideal for strengthening polymers, battery electrodes, or anti-corrosion coatings.
