Electronic-Type SWCNT Grade & Dimension Reference

Electronic-type-separated SWCNT is graded by outer diameter (OD), length and conductive-type content rather than mesh/sieve size. Grades below follow Korea New Materials' own CNT product line (koreanewmaterials.co.kr).

GradeOuter Diameter (OD)LengthPurityPackaging
HiPCO (Raw / Purified / Super-Purified)0.8–1.2 nm100–1000 nmResidual Fe catalyst <5–35 wt%500 mg
IsoNanotubes-S (semiconducting)1.2–1.7 nm300 nm–5 µm90–99% semiconducting, metal impurity <1% (pink dispersion)1 mg
