C NTs Design and Characteristics
Carbon NTs are cylindrical compounds formed from rolled-up sheets of carbon. Their design can be categorized into two main variations: 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 which the carbon sheet is rolled, dictates the nanotube's electrical properties. According on the chirality, SWNTs can be metallic or semiconducting. Additionally, their exceptional physical strength, remarkable heat conductivity, and high electrical conductivity make them highly desirable for a wide range of uses, including composites, electronics, and detectors. The aspect ratio – the ratio of length to diameter – is also important in influencing their behavior.
