Introduction to Double – walled Carbon Nanotubes
Double – walled carbon nanotubes (DWCNTs) are a unique class of carbon nanotubes consisting of two concentric single – walled carbon nanotubes. They possess a combination of excellent mechanical, electrical, and thermal properties. Their high aspect ratio, remarkable strength, and good conductivity make them highly attractive for a wide range of applications, including electronics, energy storage, composites, and sensors. Compared to single – walled carbon nanotubes (SWCNTs), DWCNTs offer better chemical stability and are more suitable for some specific applications where durability and multi – layer structure are required.
