C NTs Composition and Features
Carbon NTs 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, which describes the angle at where the graphite sheet is rolled, dictates the NT's electrical properties. According on the chirality, SWNTs can be metallic or semiconducting. Additionally, their exceptional physical strength, remarkable temperature conductivity, and high electrical conductivity make them highly valuable for a extensive range of applications, including materials, electronics, and sensors. The aspect ratio – the click here ratio of length to diameter – is also significant in influencing its behavior.
