Graphene & Fullerene
Graphene
Graphene
Graphene is an allotrope (form) of carbon. It has the following properties:


Conducts electricity
Conducts electricity
- Each carbon atom has a delocalised electron.
- Graphene is a single layer of graphite so it also conducts electricity because of the carbon atoms’ delocalised electrons.


Light but strong
Light but strong
- Graphene is 1 atom (1 layer) thick.
- This means that it is almost a 2-dimensional structure. This makes graphene very light.
- However, the strong covalent bonds between carbon atoms mean that it is also very strong.


Uses
Uses
- Graphene has lots of uses in electronics and composite materials (materials that have things added to make them more useful).
- It increases a material’s strength without adding much weight.
- It can be used in solar panels, batteries and much more.
Fullerenes
Fullerenes
Fullerenes are molecules of carbon atoms that have hollow shapes. Their structure is mainly based on hexagonal (6-sided) rings of carbon atoms, but can also contain pentagonal (5-sided) and heptagonal (7-sided) rings.


Spherical fullerenes - buckminsterfullerene
Spherical fullerenes - buckminsterfullerene
- The 1st fullerene to be discovered - buckminsterfullerene - is spherical.
- It has the formula C60.
- It is technically a simple molecule because of its fixed size.


Spherical fullerenes - uses
Spherical fullerenes - uses
- Generally speaking, spherical fullerenes come in a wide range of sizes, and their common uses include:
- Catalysts.
- Lubricants.
- Delivering drugs into the body.


Cylindrical fullerenes - shape
Cylindrical fullerenes - shape
- Carbon nanotubes are cylindrical fullerenes.
- They are often called molecular wires because they have a tiny diameter but can be incredibly long.


Cylindrical fullerenes - strength
Cylindrical fullerenes - strength
- Because of the strong covalent bonds between carbon atoms, nanotubes are exceptionally strong for their size.


Cylindrical fullerenes - uses
Cylindrical fullerenes - uses
- The strength and electrical conductivity of nanotubes make them useful:
- In electronics.
- In nanotechnology.
- For strengthening materials (e.g. tennis racket frames).
