High-Purity Carboxylated Single-Walled Carbon Nanotubes (Long)

Product Overview
High-purity carboxylated single-walled carbon nanotubes (SWCNTs) are seamless hollow cylinders formed from a single layer of graphite hexagonal lattice. These nanotubes have exceptional electrical, thermal, and mechanical properties. With a diameter typically between 1-2 nm and a length ranging from 5 to 30 micrometers, these nanotubes are produced using the moving catalytic method. The high carboxyl group content on their surface makes them ideal for high-performance materials, electronic devices, and energy systems.
