Carboxylated multi-walled carbon nanotubes (MWCNTs) offer enhanced dispersibility, optimized surface functionalization, and superior chemical reactivity. Designed for advanced applications, they enable efficient integration, extended durability, and high-performance adaptability.
Product Overview
Carboxylated multi-walled carbon nanotubes (MWCNTs) consist of several concentric layers of carbon tubes and offer excellent mechanical, electrical, and thermal properties. With a diameter of 5 to 15 nanometers and a length of 0.5 to 2 micrometers, these nanotubes are carboxylated to enhance their hydrophilicity. Due to their large surface area and unique structure, carboxylated MWCNTs are widely used in fields such as composites, electronics, catalysis, and biomedicine.
