C3.8 - Fullerenes And Graphene (Finished) Flashcards
1
Q
What are the useful features of carbon nanotubes (cylindrical fullerenes)?
A
- they have a very high tensile (stretching) strength
- high electrical conductivity and high thermal conductivity
2
Q
Why could fullerenes be used as catalysts?
A
They have a large surface to volume ratio
3
Q
Give 2 of graphene’s properties
A
- Great at conducting thermal energy
- great at conducting electricity
- extremely strong
- Very light (very low density)
4
Q
What is graphene?
A
Graphene is one layer of graphite; a sheet of carbon atoms joined together in hexagons one atom thick
5
Q
What is the medical use of fullerenes?
A
They can be used to cage other molecules which could be used to deliver a drug into the body
6
Q
What is the structure of fullerenes?
A
They are made up of carbon atoms arranged in hexagons with some pentagons and heptagons
