MWCNT Grade & Dimension Reference
MWCNT is graded by outer diameter (OD) and length rather than mesh/sieve size. Grades below follow Korea New Materials' own CNT product line (koreanewmaterials.co.kr).
| Grade | Outer Diameter (OD) | Length | Purity | Packaging |
|---|---|---|---|---|
| M1 | 20–30 nm | 1–2 µm | ≥99% | 50 g |
| M2 | 20–30 nm | 5–15 µm | ≥99% | 50 g |
| M3 | 40–60 nm | 1–2 µm | ≥99% | 50 g |
| M4 | 40–60 nm | 5–15 µm | ≥99% | 50 g |
| M5 | 80–100 nm | 1–2 µm | ≥91% | 50 g |
| M6 | 80–100 nm | 5–15 µm | ≥91% | 50 g |
| KN series (short) | 4–6 nm to >50 nm | 0.5–2 µm | >95–99.9% | 1 g |
| KN series (long) | 4–6 nm to >50 nm | 10–50 µm | >95–99.9% | 1 g |
KN-series functionalization options: hydroxylated (-OH), carboxylic (-COOH), graphitized, Ni-coated, nitrogen-doped, fluorinated, aligned, amino-modified.
