Important: MWCNT specifications vary considerably between manufacturers. Diameter, length, BET surface area, purity and D/G ratio should be reported from actual characterization data rather than treated as universal values. For a customer-facing TDS, I recommend labeling untested numbers as “Typical” or “Target” specifications.
