Carbon Nanotubes Structure and Properties
Carbon nanotubes are cylindrical structures formed from rolled-up sheets of graphite. Their structure can be categorized into two main types: single-walled NTs (SWNTs), which consist of a single layer, and multi-walled NTs (MWNTs), comprised of multiple concentric cylinders. The chirality, related describes the angle at where the graphite sheet is rolled, dictates the tube’s electrical features. Based on the chirality, SWNTs can be metallic or semiconducting. Additionally, their exceptional structural strength, remarkable heat conductivity, and high electrical conductivity make them highly desirable for a extensive range of purposes, including materials, electronics, and sensors. The aspect ratio – the ratio of length to diameter – is also important in influencing the behavior.
