graphene

Question 1

graphene

Answer 1

• single layer of graphite and its properties make it useful in electronics and composites
  -excellent conductor of heat and electricity as it has delocalised electrons that can carry a charge through the structure.
  -very strong with a high melting point - each carbon atoms forms 3 covalent bonds

Question 2

fullerenes

Answer 2

• a hollow structure made from carbon atoms
  -the first fullerene was C60 Buckminsterfullerene, also called a buckyball
• football shaped
• used to reinforce carbon fibre composites, catalysts , drug delivery in the body etc

Question 3

nanotubes

Answer 3

• long, thin tubes made of carbon, which are like rolled-up graphene sheets
• used to reinforce carbon fibre composites, catalysts , drug delivery in the body etc
