What is a fullerene?
A fullerene is a molecule made of carbon, shaped like a closed tube or hollow ball.
Name two fullerenes
Graphene C60 (buckminsterfullerene)
What are the properties of the fullerene C60?
Slippery due to weak intermolecular forces. Low melting point. Spherical. Strong covalent bonds between carbon atoms in a molecule. Large surface area.
What are the properties of graphene?
High melting point due to covalent bonding between carbon atoms. Conducts electricity because it has delocalised electrons.
Why is graphene useful in electronics?
It is extremely strong and has delocalised electrons which are free to move and carry charge. It is only one atom thick as it is a single layer of graphite.
