C Nanotubes Design and Characteristics
C NTs are cylindrical molecules formed from rolled-up sheets of carbon. Their composition can be categorized into two main variations: single-walled NTs (SWNTs), which consist of a single layer, and multi-walled nanotubes (MWNTs), comprised of multiple concentric cylinders. The chirality, related describes the angle at that the carbon sheet is rolled, dictates the nanotube's electrical characteristics. Based on the chirality, SWNTs can be metallic or semiconducting. Additionally, their exceptional mechanical strength, remarkable heat conductivity, and high electrical conductivity make them highly desirable for a broad range of uses, including blends, electronics, and sensors. The aspect ratio – the ratio of length to diameter – is also significant in influencing the behavior.
