Graphitized hydroxylated multi-walled carbon nanotubes (MWCNTs) offer optimized surface functionalization, enhanced structural stability, and superior electrical conductivity. Designed for advanced applications, they ensure efficient dispersion, extended durability, and high-performance adaptability.
Product Overview
Graphitized hydroxylated multi-walled carbon nanotubes are carbon nanotubes prepared by the chemical vapor deposition (CVD) method, followed by high-temperature graphitization. This treatment effectively removes catalysts and impurities, enhancing the purity and improving the microstructure of the nanotubes. The graphitization process increases the crystallinity of the carbon nanotubes, leading to improved thermal stability, electrical conductivity, and other properties. These carbon nanotubes are ideal for high-performance applications, and due to their hydroxyl groups, they possess excellent chemical modifiability, making them suitable for further functionalization and diverse applications.
