Carbon Nanotubes Design and Characteristics
C NTs are cylindrical molecules formed from rolled-up sheets of carbon. Their composition can be categorized into two main types: single-walled nanotubes (SWNTs), which consist of a unique layer, and multi-walled NTs (MWNTs), comprised of multiple concentric cylinders. The chirality, related describes the angle at which the graphite sheet is rolled, dictates the NT's electrical properties. According on the chirality, SWNTs can be metallic or semiconducting. Moreover, their exceptional structural strength, remarkable thermal conductivity, and high electrical conductivity make them highly attractive for a wide range of purposes, including composites, electronics, and detectors. The read more aspect ratio – the ratio of length to diameter – is also significant in influencing the behavior.
