Description
Single-Walled Carbon Nanotubes (SWCNTs, SWNTs) – Purity > 90%
Single-walled carbon nanotubes (SWCNTs) are cylindrical carbon nanostructures consisting of a single layer of graphene rolled into a tube. With diameters in the nanometer range and lengths up to tens of micrometers, SWCNTs demonstrate extraordinary mechanical strength, electrical conductivity, and thermal stability. These unique characteristics position them as indispensable materials across various industries.
The SWCNTs listed here are produced using a chemical vapor deposition (CVD) process and feature high carbon purity, minimal ash content, and excellent conductivity. Due to their outstanding properties, they find wide applications in nanotechnology, electronics, energy storage, composites, and even medical devices.
