Ultra-High Purity Carboxylated Single-Walled Carbon Nanotubes (SWCNTs)

Product Overview
Ultra-high purity carboxylated single-walled carbon nanotubes (SWCNTs) are seamless hollow tubes formed by wrapping a single layer of graphite hexagonal lattice. These nanotubes have a very high aspect ratio and exceptional electrical, mechanical, and thermal properties. Typically, their diameter ranges from 1 to 2 nanometers, and their length can extend to micrometer scale or even longer. They are widely used in electronics, energy storage, composite materials, and sensors. This material has high purity and is produced via the floating catalyst method, with carboxylation treatment enhancing its compatibility with other materials.
