fullerines and nanotubes

Graphene is a single layer of

Graphite

Graphene properties

• Strong covalent bonds mean hight melting and boiling point

• Very strong

• Can conducet

Fullerines are

Molecules of carbon atoms with hollow shapes

Bucky balls properties

• Made up of 60 carbon atoms

• Spherical

• Weak intermolecular forces mean low melting and boiling point

• Slippery

Nanotube properties

• Graphene rolled into a cylinder

• Very high length to diameter ratio

• High tensile streanght

• Strong

• Conduct

Polymer defenition

a large molecule formed from many smaller ones known as monomers

Atoms in polymers are joined by

Strong covalent bonds

One example of a polymer is

Polyethene

Properties of polymers

• Strong intermolecular forces

• Higher melting and boiling points than substances with small molecules.
