Economical Uses of Chemically Modified Carbon Nanotubes

Nanotechnology has led to significant changes in basic materials. With advancements in the technology, nanomaterial sensors have been fabricated that play a major role in various fields. Fabricating the materials in nanoscale lays the foundation for the nanotechnology field. Carbon nanotubes (CNTs) are tube-like structures having carbon as a constituent material with a diameter in nanometer scale. CNTs are originated from graphite sheets in the form of layers, which are similar to rolled-up non-breakable hexagonal mesh-like structures. The carbon molecules are at the corners of the hexagonal structures. The size of carbon nanotubes varies from single-walled (SWCNTs) to double-walled (DWCNTs) to multi-walled carbon nanotubes (MWCNTs). CNTs can be prepared through electric arc, chemical vapor deposition, and laser deposition. Due to their exceptional properties such as low density, high elasticity, and high thermal conductivity, CNTs play an important role in many fields such as sensing, wastewater treatment, optics, electronics, and, of course, in nanotechnology.
