Really small particles, they include fallerenes and are made of carbon arranged in hexagonal rings.

What are fullerenes?
Molecules of carbon that can be joined together to form nanotubes.
2 of 6
What are the properties of nanoparticles?
large surface area : volume so can be used for catalysts. They conduct electricity, and are ligher and stronger than most building materials.
3 of 6
What are the properties of thermosoftening polymers?
Don't have crosslinking between chains, easy to melt. Can be moulded and remoulded into a new shape.
4 of 6
What are the properties of thermosetting polymers?
Have crosslinks between chains, solid structure, doesn't soften when heated, strong, hard, rigid.
5 of 6
What are the types of polythene?
Low density: heating ethene to 200 degrees under high pressure. Flexible. High density: heating ethene at a lower temperature and pressure (with catalyst). more rigid.
