Low-purity single-walled carbon nanotubes (SWCNTs) offer basic electrical conductivity, moderate dispersion stability, and standard mechanical reinforcement. Suitable for general-purpose applications, they provide cost-effective material integration, adaptable formulation, and functional performance.
Product Overview
Low-purity single-walled carbon nanotubes (SWCNTs) are seamless hollow tubes formed by a single layer of graphite hexagonal lattice, typically with a diameter of 1-2 nm and lengths ranging from 5 to 30 micrometers. They have a large aspect ratio and excellent electrical, thermal, and mechanical properties. These nanotubes are produced by the moving catalytic method, with high electrical conductivity, making them ideal for applications requiring high conductivity.
