Carbon Nanotubes Structure and Features
C NTs are cylindrical structures formed from rolled-up sheets of carbon. Their structure can be categorized into two main variations: single-walled nanotubes (SWNTs), which consist of a single layer, and multi-walled NTs (MWNTs), comprised of multiple concentric cylinders. The chirality, related describes the angle at that the graphite sheet is rolled, dictates the nanotube's electrical characteristics. Depending on the chirality, SWNTs can be metallic or semiconducting. Furthermore, their exceptional structural strength, remarkable thermal conductivity, and high electrical conductivity make them highly attractive for a broad range of uses, including composites, electronics, and probes. The aspect ratio – the ratio of length to diameter – is also important in influencing their behavior.
