C NTs Composition and Properties
Carbon nanotubes are cylindrical compounds formed from rolled-up sheets of graphite. Their structure can be categorized into two main variations: single-walled NTs (SWNTs), which consist of a one layer, and multi-walled NTs (MWNTs), comprised of multiple concentric cylinders. The chirality, related describes the angle at where the carbon sheet is rolled, dictates the NT's electrical characteristics. According on the chirality, SWNTs can be metallic or semiconducting. Moreover, their exceptional physical strength, remarkable heat conductivity, and high electrical conductivity make them highly attractive for a broad range of purposes, including blends, electronics, and detectors. The aspect ratio – the ratio of length to diameter – is also important in influencing the behavior.
