Carbon NTs Structure and Characteristics
C nanotubes are cylindrical molecules formed from rolled-up sheets of graphite. Their composition can be categorized into two main types: single-walled NTs (SWNTs), which consist of a unique layer, and multi-walled nanotubes (MWNTs), comprised of multiple concentric cylinders. The chirality, related describes the angle at where the graphite sheet is rolled, dictates the NT's electrical characteristics. Depending on the chirality, SWNTs can be metallic or semiconducting. Additionally, their exceptional mechanical strength, remarkable thermal conductivity, and high electrical conductivity make them highly valuable for a broad range of uses, including blends, electronics, and probes. The aspect ratio – the ratio of length to diameter – is also significant in influencing its behavior.
