Carbon NTs Structure and Characteristics
Carbon NTs are cylindrical compounds formed from rolled-up sheets of carbon. Their design 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 which the carbon sheet is rolled, dictates the NT's electrical characteristics. Depending on the chirality, SWNTs can be metallic or semiconducting. Additionally, their exceptional mechanical strength, remarkable temperature conductivity, and high electrical conductivity make them highly valuable for a broad range of applications, including blends, electronics, and probes. The aspect ratio – the ratio of length to diameter – is also significant in influencing its behavior.
