C NTs Structure and Characteristics
C nanotubes are cylindrical compounds formed from rolled-up sheets of graphite. Their structure can be categorized into two main types: single-walled NTs (SWNTs), which consist of a unique layer, and multi-walled NTs (MWNTs), comprised of multiple concentric cylinders. The chirality, related 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. Furthermore, their exceptional structural strength, remarkable temperature conductivity, and high check here electrical conductivity make them highly attractive for a wide range of purposes, including blends, electronics, and probes. The aspect ratio – the ratio of length to diameter – is also important in influencing their behavior.
