Research is actively exploring their applications across a broad spectrum of industries, extending from electronics and energy storage to biomedicine and advanced composites. The manufacturing processes, however, are often intricate, and controlling the size and configuration of these nano carbon structures remains a key barrier to widespread adoption. Further development necessitates a thorough understanding of their synthesis, properties, and potential environmental impact, particularly as production increases and integration into consumer products becomes more widespread. Future advancements promise to unlock even more astonishing capabilities through innovative design and improvement techniques.
C NTs Structure and Properties
C NTs are cylindrical compounds formed from rolled-up sheets of graphite. Their design can be categorized into two main types: single-walled NTs (SWNTs), which consist of a single layer, and multi-walled nanotubes (MWNTs), comprised of multiple concentric cylinders. The chirality, that describes the angle at that the carbon sheet is rolled, dictates the nanotube's electrical characteristics. Depending on the chirality, SWNTs can be metallic or semiconducting. Moreover, their exceptional physical strength, remarkable heat conductivity, and high electrical conductivity make them highly valuable for a extensive range of uses, including materials, electronics, and probes. The aspect ratio – the ratio of length to diameter – is also crucial in influencing its behavior.
