Low-purity carboxylated single-walled carbon nanotubes (SWCNTs) offer basic functionalization, moderate dispersion stability, and standard conductivity. Suitable for general-purpose applications, they provide cost-effective material integration, adaptable formulation, and functional enhancement.
Product Overview
Low-purity carboxylated single-walled carbon nanotubes (SWCNTs) are seamless hollow tubes formed by the helical winding of a single layer of graphite hexagonal lattice along a chiral vector. These nanotubes have a very high surface area and excellent physical and chemical properties. They are produced using chemical vapor deposition (CVD) and exhibit good electrical and thermal conductivity. Despite their relatively lower purity, they still maintain significant electrical and mechanical properties, with strong adaptability and potential when subjected to certain surface modifications. These nanotubes are widely used in electronics, energy, composite materials, and other fields.
