C Nanotubes Composition and Features
Carbon nanotubes are cylindrical structures formed from rolled-up sheets of graphene. Their structure can be categorized into two main variations: single-walled NTs (SWNTs), which consist of a one layer, and multi-walled NTs (MWNTs), comprised of multiple concentric cylinders. The chirality, that describes the angle at where the graphite sheet is rolled, dictates the NT's electrical properties. Based on the chirality, SWNTs can be metallic or semiconducting. Moreover, their exceptional physical strength, remarkable temperature conductivity, and high electrical conductivity make them highly desirable for a broad range of purposes, including materials, electronics, and sensors. The aspect ratio – the ratio of length to diameter – is also crucial in influencing its behavior.
