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