Carbon nanoparticles Flashcards
1
Q
What is the common name for buckminsterfullerene?
A
Buckyball. It is an allotrope of carbon.
2
Q
Properties of buckyball.
A
- low sublimation point
- relatively soft
- poor conductor of electricity
- slightly soluble in solvents
3
Q
Uses of buckyball.
A
Medical purposes as the drug molecules can be trapped in the cage to carry the medicine and delivered it to specific places.
4
Q
properties of graphene
A
- most chemically reactive form of carbon
- burn at very low temperatures and much more reactive than graphite
- extremely strong for its mass
- conducts electricity and heat much better than graphite
5
Q
Uses of graphene.
A
Use in tiny electrical circuits and for tiny transistors, touchscreens, solar cells and other energy storage devices
6
Q
What are nanotubes?
A
fullerenes of hexagonally arranged carbon atoms like single layer of graphite bent into the form of a cylinder
-resembles a rolled-up sheet of graphite
7
Q
Characteristic of nanotubes.
A
- high electrical conductivity
- 100x stronger than the steel of the same thickness but 6x lighter
- high mp because strong covalent bonds
8
Q
Uses of carbon nanotubes
A
- production of car and airplane
- adsorb hydrogen gas on their surfaces
