Carbon Nanotubes Composition and Properties

Carbon NTs are cylindrical structures formed from rolled-up sheets of graphite. Their structure can be categorized into read more two main types: single-walled NTs (SWNTs), which consist of a one layer, and multi-walled nanotubes (MWNTs), comprised of multiple concentric cylinders. The chirality, that describes the angle at which the carbon sheet is rolled, dictates the nanotube'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 valuable for a broad range of purposes, including composites, electronics, and sensors. The aspect ratio – the ratio of length to diameter – is also significant in influencing the behavior.
