Graphene And Fullerenes

Question 1

What are fullerenes characterised by?

Answer 1

They are made of carbon (rings) and they form hollow structures either like cages or like cylinders e.g nanotubes

Question 2

What are properties of fullerenes?

Answer 2

High tensile strength
Good conducter of electricity
Unreactive
Large surface area to volume ratio

Question 3

What are uses of fullerenes?

Answer 3

Reinforcing materials e.g sports equipment
Electronics, chips and curved screens
Drug delivery in the body
Lubricants and catalysts

Question 4

What is graphene?

Answer 4

Single layer of graphite, 1 atom thick, 2D structure because it’s flat

Question 5

What are graphene properties?

Answer 5

Very low density
Strong for its mass
Electrical conductor
Flexible

This properties make it exciting for developing new technologies such as flexible screens

Question 6

What is the molecular formula for buckminsterfullerene

Answer 6

C60
