Fullerenes

Cards (10)

  • What are polymers and what are they made of?
    ā˜… They are very large molecules
    ā˜… They are made up of lots of smaller monomers
  • Properties, bonds and forces in polymers
    ā˜… Polymers atoms are linked together by strong covalent bonds
    ā˜… The intermolecular forces are relatively strong
    š¬½ These molecules are solid at room temperature
  • Structure of all fullerenes?
    ā˜… Hexagonal carbon atoms (sometimes in groups of 5 or 7)
    ā˜… Hollow in the centre
  • Date of Buckminsterfullereneā€Ø
    ā˜… First fullerene to be discovered
  • How many carbon atoms does BuckminsterFullerene contain?
    60
  • What shape is BuckminsterFullerene?ā€Ø
    sphere
  • Uses of BuckminsterFullereneā€Ø
    ā˜… Used for drug (such as pharmaceuticals) delivery into the body
    ā˜… Used as lubricants (to remove friction between moving parts)
    ā˜… Catalysts in chemical reactions
  • Shape of carbon nanotubes
    ā˜… Cylindrical
  • Properties of carbon nanotubes
    ā˜… High tensile strength (stretch a lot without breaking)
    ā˜… Good conductors of heat & electricity (delocalised electrons)
  • Use of carbon nanotubes
    ā˜… To reinforce materials (e.g. in tennis rackets)
