hiilinanotubien
Hiilinanotubien, or "carbon nanotubes," are allotropic forms of carbon with a cylindrical nanostructure composed of rolled-up sheets of graphene. Their unique properties make them highly significant in materials science and nanotechnology. Discovered in 1991 by Sumio Iijima, they exhibit exceptional strength, electrical conductivity, and thermal conductivity, often surpassing those of traditional materials like steel or copper.
Carbon nanotubes can be single-walled (SWCNTs), consisting of a single sheet of graphene rolled into a tube,
Applications of carbon nanotubes span multiple industries. In electronics, they are used in transistors, sensors, and
Despite their potential, challenges remain in large-scale production, cost-effectiveness, and ensuring safety, particularly regarding potential toxicity.
