Carbon NTs Composition 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 one layer, and multi-walled NTs (MWNTs), comprised of multiple concentric cylinders. The chirality, which describes the angle at that the graphene sheet is rolled, dictates the nanotube's electrical properties. Depending 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 extensive range of purposes, including blends, electronics, and probes. The aspect ratio – the ratio of length to diameter – is also significant in influencing their behavior.
