Graphene and fullerenes

Question 1

Graphene definition

Answer 1

single layer of graphite - hexagonal rings of carbon atoms

Question 2

Fullerenes definition

Answer 2

large molecule of carbon atoms with a hollow space inside

Question 3

What are the 2 types of fullerenes

Answer 3

nanospheres and nanotubes

Question 4

Graphene uses and why

Answer 4

Phone screen = transparent, strong, flexible, scratch resistant
Microchips and phone batteries = low density, electrical conductor
Catalyst = large surface area to volume ratio

Question 5

Fullerenes uses and why

Answer 5

Reinforcing material = high tensile strength, high melting point
Lubricants = slide over each other
Microchips and phone batteries = electrical conductor
Catalyst = large surface area
Medical uses = doesn’t cause an immune response in the body, hollow
