On a molecular level, CNTs are 100 times stronger than steel at one-sixth the weight and have a very large aspect ratio making them very useful as a mechanical property enhancing filler material.Ĭarbon Nanotubes conduct heat and electricity similar to copper but without oxidative concerns provided that they are well dispersed.Ĭarbon Nanotubes have already found commercial applications in the fields of engineering plastics, polymers, displays, anti corrosion paints, thin films and coatings, transparent and non-transparent conductive electrodes, super hydrophobic coatings and anti-static packaging while active research is on going in fields such as batteries, fuel cells, solar cells, advanced devices, optics, water desalination and many others.Ĭarbon Nanotubes paved the way for Graphene.Īllotropes Of Carbon Featuring Diamond, Graphite, and Carbon Nanotubesīeing a tube-like material. Our carbon nanotubes overview is designed to give the reader an in depth understanding of these amazing materials. In fact, a 4th state of matter was recently discovered as water trapped inside a carbon nanotube doesn’t act as a solid, liquid, or gas. These functional nanoscale materials have a variety of unique, fascinating, and never seen before properties. Hundreds of millions of dollars have been invested trying to unlock the secrets of these revolutionary materials. Since the discovery of carbon nanotubes (CNTs) in 1991 by Iijima, a whole new discipline in materials science has developed, Nanoscience.

Like graphene, carbon nanotubes can conduct electricity because it contains delocalised electrons which are free to move throughout the single sheet of carbon atoms and carry charge.

Carbon nanotubes are good conductors of electricity.

This property is useful when making composite materials which can be used for tension racquets. This is because they have a very high length to diameter ratio. Nanotubes are able to withstand high tension when being stretched and do not break.

Carbon nanotubes have high tensile strength.

These nanotubes are much longer than they are wide, therefore they have a high length to diameter ratio. Fullerenes can form thin cylinders known as carbon nanotubes.

Carbon nanotubes are cylindrical fullerenes.

Buckminsterfullerene is slippery because between molecules of buckminsterfullerene there are weak intermolecular forces which allow molecules of this fullerene to slide past each other.

Buckminsterfullerene (C60) is slippery.

Buckminsterfullerene has a low melting point because between molecules of buckminsterfullerene there are weak intermolecular forces that require little energy to overcome.

Buckminsterfullerene (C60) has a low melting point.

This property means graphene can be used in electronics. Graphene properties include electric al conductionbecause it contains delocalised electrons which are free to move throughout the single sheet of carbon atoms and carry charge. These properties allow graphene to be added to other substances to increase their strength without increasing their weight forming a composite. These covalent bonds are difficult to overcome and require a lot of energy. Graphene is extremely strong due to the many, strong covalent bonds between the carbon atoms.

Graphene is very strong and has a low density.

Graphene is a single carbon atom thick forming a two-dimensional sheet.

Graphen e is made up of a single layer of hexagonal rings, with each carbon atom bonded to three other carbon atoms meaning each carbon atom has one delocalised electron (like graphite). Graphene is a single layer of graphite.Graphene & Fullerenes (GCSE Chemistry) What is Graphene?
