C NTs Structure and Features
C nanotubes are cylindrical molecules formed from rolled-up sheets of carbon. Their design can be categorized into two main types: single-walled NTs (SWNTs), which consist click here of a single layer, and multi-walled NTs (MWNTs), comprised of multiple concentric cylinders. The chirality, related describes the angle at which the graphite sheet is rolled, dictates the nanotube'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 extensive range of applications, including composites, electronics, and sensors. The aspect ratio – the ratio of length to diameter – is also crucial in influencing their behavior.
