What is properties of carbon nanotubes?

What is properties of carbon nanotubes?

CNTs have extraordinary electrical conductivity, heat conductivity, and mechanical properties. They are probably the best electron field-emitter possible. They are polymers of pure carbon and can be reacted and manipulated using the well-known and tremendously rich chemistry of carbon.

What is the structure and properties of carbon nanotubes?

Most of the physical properties of carbon nanotubes derive from graphene. In graphene, carbon atoms are densely organized in a regular sp2-bonded atomic-scale honeycomb (hexagonal) pattern, and this pattern is a basic structure for other sp2 carbon bonded materials (allotropes) such as fullerenes and carbon nanotubes.

What is the full form of SWNT?

The Full Form of SWNT is Single-walled nanotubes. Single walled carbon nanotubes (SWCNTs) can be considered as a single long wrapped graphene sheet. Nanotubes generally have a length to diameter ratio of about 1000 and hence considered nearly one-dimensional structures.

What are different types of CNTs?

In addition to the two different basic structures, there are three different possible types of carbon nanotubes. These three types of CNTs are armchair carbon nanotubes, zigzag carbon nanotubes, and chiral carbon nanotubes.

What are carbon nanotubes useful for?

Carbon nanotubes have been first used as additives to various structural materials for electronics, optics, plastics, and other materials of nanotechnology fields. Since the beginning of the 21st century, they have been introduced in pharmacy and medicine for drug delivery system in therapeutics.

How are carbon nanotubes used in medicine?

Applications of Carbon Nanotubes in Pharmacy and Medicine. The main applications of CNTs in pharmacy and medicine include drug, biomolecule, gene delivery to cells or organs, tissue regeneration, and biosensor diagnostics and analysis. Drug is fixed on the surface or the inside of functionalized CNTs.

What is decoration of multiwall carbon nanotubes ( MWCNT )?

Decoration of multiwall carbon nanotubes (MWCNTs) consists of depositing nanoparticles on the MWCNT walls or ends, bonded by physical interaction with potential applications in catalysis, biosensors, biomedical, magnetic datastorage, and electronic devices.

What’s the difference between a SWCNT and a MWCNT?

MWCNTs consist of multi rolled layers of graphene inserted one into the other and the number of graphene walls may reach more than 25 walls with spacing of 0.34 nm. The outside diameter of MWCNTs ranges from 1 nm to 50 nm while the inside diameter is several nanometers.

What makes a carbon nanotube a wonder material?

The unique structure of carbon nanotube, combined with its unique mechanical and electrical properties makes it a ‘wonder material’ in the real sense. A single-walled carbon nanotube (SWCNT) is a seamless cylinder which consists of only one layer of graphene.

Which is stronger single walled or multi walled carbon nanotubes?

Research studies have proven that multi-walled carbon nanotubes are remarkably stronger than the impressively strong single-walled carbon nanotube. It also shows that multi-walled carbon nanotubes are significantly better at working in the highly corrosive atmosphere.
