C NTs Composition and Features
C nanotubes are cylindrical molecules formed from rolled-up sheets of graphene. Their structure can be categorized into two main variations: 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 which the graphite sheet is rolled, dictates the tube’s electrical properties. Based on the chirality, SWNTs can be metallic or semiconducting. Additionally, their exceptional structural strength, remarkable thermal conductivity, and high electrical conductivity make them highly valuable for a broad range of applications, including composites, electronics, and detectors. The aspect ratio – the ratio of length to diameter – is also important in influencing the behavior.
