Graphitized carboxylated multi-walled carbon nanotubes (MWCNTs) offer optimized crystallinity, enhanced surface functionalization, and superior electrical conductivity. Designed for advanced applications, they ensure efficient dispersion, extended durability, and high-performance adaptability.
Product Overview
Graphitized carboxylated multi-walled carbon nanotubes are produced through the chemical vapor deposition (CVD) method and undergo high-temperature graphitization to remove catalysts and impurities. This process enhances the purity of the carbon tubes and improves their microstructure. The graphitization treatment improves the electrical conductivity, thermal conductivity, and mechanical properties of the carbon nanotubes, allowing them to maintain good stability even in high-temperature environments. The higher the graphitization level, the better the crystallinity of the nanotubes, leading to improved thermal stability and conductivity.
