Summary:
This is a review paper that summarizes some brief information about carbon nanotubes (CNTs).
Carbon nanotube is among the allotropes of pure carbon which include diamond, graphite, and amorphous noncrystalline structures. If a flat sheet of graphene is coiled to become a hollow cylinder, the CNT structure is formed. CNTs were found to have good electronic, electrical, and mechanical properties. They have high aspect ratio, high tensile strength, low mass density, high heat conductivity, larger surface area, and versatile electronic behavior.
Different techniques for fabricating CNTs were also discussed. The differences, advantages, and disadvantages of the electric arc discharge, laser ablation, and chemical vapor deposition methods were presented. Chemical vapor deposition was highlighted as the CNT fabrication method which can be scaled up for large-scale and high-quality CNT production at a relatively low cost.
Finally, the applications of CNTs were illustrated. CNTs are currently used for field emission and hydrogen storage, used as solar cells and constituents of composite materials.
Contribution and application:
This paper summarized information about actual CNTs so that it would be easier to connect modeled CNTs to real ones. By reviewing the properties and fabrication methods of CNTs, it would be easier to see the practicality and difficulty of using CNTs in water treatment.
