Carbon NTs Structure and Properties
C NTs are cylindrical molecules formed from rolled-up sheets of carbon. Their design can be categorized into two main kinds: single-walled nanotubes (SWNTs), which consist of a single layer, and multi-walled NTs (MWNTs), comprised of multiple concentric cylinders. The chirality, related describes the angle more info at where the graphite sheet is rolled, dictates the NT's electrical features. Based on the chirality, SWNTs can be metallic or semiconducting. Moreover, their exceptional mechanical strength, remarkable heat conductivity, and high electrical conductivity make them highly attractive for a broad range of uses, including blends, electronics, and sensors. The aspect ratio – the ratio of length to diameter – is also crucial in influencing the behavior.
