Section 4: Small carbon- based structures Flashcards
What are 3 small carbon based structures?
Fullerene, nanotube and graphene
What is the structure of fullerene like?
Hollow- shaped, cage like structures and tubes which also contain hexagonal rings. Example: Buckminster fullerene (C60)
What are the properties of fullerene?
Very strong. Hollow so can contain other chemicals within it.
What are the uses for fullerene?
Drug delivery, lubricants, catalysts (large surface area to volume ratio) and in electronics.
What is the structure of graphene like?
A single layer of graphite. ( one atom thick)
what are the properties of graphene?
Very strong and light. Has delocalised electrons so it is able to conduct electricity.
What are the uses for graphene?
Electronics, composites
What is the structure of a carbon nanotube like?
Cylindrical tubes of carbon atoms that are very long compared to the diameter.
What are the properties of a carbon nanotube?
Very strong, light and flexible. Has delocalised electrons so it is able to conduct electricity.
What are the uses for a carbon nanotube?
Nanotechnology, electronics, reinforcing. For example: tennis rackets.
