SWCNT Grade & Dimension Reference

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

GradeOuter Diameter (OD)LengthPurityPackaging
High-purity grade<2 nm5–30 µm>95% (SSA >1075 m²/g on high-surface-area grade)500 mg–1 g
Industrial grade1–2 nm5–30 µm>60%1 g

Functionalization / dispersion options: hydroxylated (-OH), carboxylic (-COOH), amino-modified; ODA / PEG / PABS surface-coated dispersions (65–80% SWCNT content).

Information Required for Quotation

  • Grade (High-purity or Industrial) / purity (e.g. >95% or >60%)
  • Outer diameter (OD) range
  • Length
  • Functionalization or dispersion type, if required (-OH, -COOH, amino-modified, ODA/PEG/PABS dispersion)
  • Quantity
  • Application environment
  • Required delivery country
Lead time depends on grade, OD/length range, functionalization and quantity. Export availability can be reviewed based on destination country and material type. A Certificate of Analysis can be provided on request.
