Graphene & Fullerenes

Cards (8)

  • Graphene is a single layer of graphite with very strong covalent bonds. It can be used to make different shapes which we call fullerenes. As each atom donates one electron to a pool of delocalised electrons, graphene can also conduct electricity.
  • Graphene is completely natural but scientists make strong thin sheets of it to form tubes, pentagons and hexagons (which are made into spheres)
  • Scientists can form the spheres of fullerenes around other molecules such as drugs, so that it acts like a cage and can be used to deliver the drugs to certain areas of the body.
  • Fullerenes have a large surface area to volume ratio so they can be used to make industrial catalysts.
  • The tubes known as 'nanotubes' can be used in nanotechnology and electronics because they can conduct electricity.
  • Fullerenes are also used to strengthen materials as they have a very high length:diameter ratio, which adds a lot of strength without weight.
  • Buckminster fullerene
    • Very first fullerene
    • Hollow sphere made of 60 carbon atoms
    • C60
  • We call technology that uses these tiny structures nanotechnology which is now used in loads of industries such as medicine, batteries, fashion and even food.
