CARBON NANOTUBES – AN OVERVIEW
Journal Title: International Journal of Pharmaceutical Development & Technology - Year 2014, Vol 4, Issue 1
Abstract
Carbon nanotubes are the unique tubular structures with nanometer scale for measuring diameter. The nanotubes contain one up to tens and hundreds of concentric shells of carbons with adjacent shell separation. The carbon network of the shells is considered closely related to the honeycomb arrangement of the carbon atoms in graphite sheets. Amazing thermal, mechanical and electronic properties of the nanotubes appear in their structure and also in the graphite-like arrangement of the carbon atoms in shells. The carbon nanotubes have high Young’s modulus and tensile strength, which makes them preferable for composite materials with extended mechanical properties. The carbon nanotubes may exhibit metallic or semiconducting nature depending on their structural parameters. These properties make a way for application of the carbon nanotubes as central elements in electronic devices including field-effect transistors (FET), single-electron transistors and rectifying diodes. These tiny structures also find their way in different applications that touch nearly every field of technology, including aerospace, electronics, medicine, defense, automotive, energy, construction, and even fashion. Carbon nanotubes are also proved to be helpful in drug delivery due to their potent drug targeting property.
