This product is a high-purity (≥95%) nanoscale multi-walled carbon nanotube (MWCNT) with a tube diameter range of 6–15 nm (typical values 8–12 nm) and a length distribution from hundreds of nanometers to several micrometers (controllable). It features a typical multi-layer wall structure (3–30 layers), high degree of graphitization, and excellent electrical and thermal conductivity. The surface can be purified (to remove amorphous carbon and residual metal catalysts) and selectively functionalized (such as carboxyl or hydroxyl modifications).

Core Advantages

1. High Purity and Uniformity: Metal impurity content ≤0.1 wt% (very low residual catalysts such as iron/nickel), carbon nanotube purity ≥95% (up to 98% for some models), and concentrated tube diameter distribution (over 90% within the 6–15 nm range), ensuring consistent performance.

2. Nanoscale fine structure: tube diameters of 6–15 nm (close to the scale of single-walled carbon nanotubes), combining the mechanical strength of multi-walled tubes with the size effects of small dimensions, easily dispersible in microscopic composite systems, and can significantly enhance the functional density of the matrix material.
