C Nanotubes Design and Properties
C NTs are cylindrical structures formed from rolled-up sheets of graphite. Their design can be categorized into two main types: single-walled NTs (SWNTs), which consist of a one layer, and multi-walled NTs (MWNTs), comprised of multiple concentric cylinders. The chirality, which describes the angle at which the graphite sheet is rolled, dictates the tube’s electrical properties. Depending on the chirality, SWNTs can be metallic or semiconducting. Furthermore, their exceptional structural website strength, remarkable temperature conductivity, and high electrical conductivity make them highly attractive for a extensive range of purposes, including blends, electronics, and sensors. The aspect ratio – the ratio of length to diameter – is also crucial in influencing its behavior.
