History of Carbon Nano Technology
The discovery of carbon nano technology dates back to the 1960s when scientists first observed carbon buckyballs, hollow, soccer-ball-shaped molecules made of 60 carbon atoms. However, it wasn’t until the discovery of carbon nanotubes (CNTs) in 1991 that the field began to gain momentum. CNTs were found to have exceptional mechanical, thermal, and electrical properties, making them ideal for a wide range of applications.
The early 2000s saw a surge in research on carbon nano materials, led by scientists such as Andre Geim and Konstantin Novoselov, who discovered graphene, a single layer of carbon atoms arranged in a hexagonal lattice. This discovery opened up new avenues for research on carbon nano materials, and the field has continued to evolve at a rapid pace.
