5.2.3.3 graphene and fullerenes Flashcards
1
Q
What is graphene
A
Grapheme is a single layer of graphite and has properties that make it useful in electronics and composites.
2
Q
What are fullerenes
A
They are molecules of carbon atoms with hollow shapes
3
Q
What is the structure of fullerenes
A
Based on hexagonal rings of carbon atoms but they may also contain rings with five or seven carbon atoms
4
Q
What was the first fullerene and it’s shape
A
Buckminsterfullerene (C60) which has a spherical, shape
5
Q
What are carbon nanotubes and what are they useful for
A
The are cylindrical fullerenes with very high length to diameter ratios, their properties make them useful for nanotechnology, electronics and materials
