C Nanotubes Composition and Features
Carbon NTs are cylindrical molecules formed from rolled-up sheets of carbon. Their composition can be categorized into two main kinds: single-walled NTs (SWNTs), which consist of a single layer, and multi-walled nanotubes (MWNTs), comprised of multiple concentric cylinders. The chirality, that describes the angle at that the carbon sheet is rolled, dictates the tube’s electrical characteristics. According on the chirality, SWNTs can be metallic or semiconducting. Additionally, their exceptional mechanical strength, remarkable heat conductivity, and high electrical conductivity make them highly valuable for a wide range of purposes, including composites, electronics, and sensors. The aspect ratio – the ratio of length to diameter – is also significant in influencing its behavior.
