What are the chemical properties of fullerene?
Fullerenes are molecules composed entirely of carbon with spherical (buckyballs), ellipsoid, tubular (nanotubes) or a combination shape (nanobuds). They consist of hexagonal and pentagonal (sometimes also heptagonal) rings, with the latter necessary for the curvature of the molecule.

What is a fullerene and its uses?
Fullerene is able to fit inside the hydrophobic cavity of HIV proteases, inhibiting the access of substrates to the catalytic site of enzyme. It can be used as radical scavenger and antioxidant. In addition, fullerenes have been used as a carrier for gene and drug delivery systems.
What are 3 uses of fullerenes?
It has various applications such as surface coating, conductive devices, and the creation of molecular networks. In addition, within the field of medicine, a water-soluble fullerene showed activity against Human Immunodeficiency viruses that cause AIDS, it can even be used as an antioxidant.
What are Graphenes properties?
The most outstanding properties of graphene are:
- High thermal conductivity.
- High electrical conductivity.
- High elasticity and flexibility.
- High hardness.
- High resistance.
- Ionizing radiation is not affected.
- Able to generate electricity by exposure to sunlight.
- Transparent material.
Why is fullerene an insulator?
Some said that, “Fullerne do not have layered structure like graphit and that is why free electrons do not jump and move easily . Thus, Fullerene is a bad conductor of electricity/ insulator. “
Is fullerene hard or soft?
The fullerene molecule has excellent mechanical rigidity. At the same time, the fullerite crystal is a soft material under normal conditions, but becomes harder than diamond under pressure (due to the 3-D polymerization).
What are the physical and chemical properties of graphene?
One of the most useful properties of graphene is that it is a zero-overlap semimetal (with both holes and electrons as charge carriers) with very high electrical conductivity. Carbon atoms have a total of 6 electrons; 2 in the inner shell and 4 in the outer shell.
What is the difference between a fullerene and graphene write its properties and uses?
Graphene is an allotrope of carbon that occurs as sheets of carbon while fullerene is an allotrope of carbon which occurs as spheres of carbon. The key difference between graphene and fullerene is that graphene has a two-dimensional structure, while fullerene has a three-dimensional structure.
Are fullerenes conductive?
To reiterate Ivan’s comment fullerene is a bad conductor because that’s what the measured properties produce as a result. The mechanism that makes it a bad conductor is that it has shorter range continuity than graphite. In graphite the carbon is made of sheets that can be as long as the sample.
Why is fullerene slippery?
There are weak intermolecular forces between molecules of buckminsterfullerene. These need little energy to overcome, so buckminsterfullerene is slippery and has a low melting point.
What are the physical properties of graphene?
Graphene properties
- High thermal conductivity.
- High electrical conductivity.
- High elasticity and flexibility.
- High hardness.
- High resistance.
- Ionizing radiation is not affected.
- Able to generate electricity by exposure to sunlight.
- Transparent material.
What are the uses of fullerene?
Antioxidants. Fullerenes can make excellent antioxidants,this property can be attributed to the large number of conjugated double bonds they possess and a very high electron affinity of these molecules
What is fullerene used for?
Fullerenes can be used as organic photovoltaics (OPV), these are powerful antioxidants, reacting readily and at a high rate with free radicals which are often the cause of cell damage or death. Other uses of C 60 like catalysts, in water purification and biohazard protection, portable power, vehicles and medical.
What are fullerenes used for?
Fullerenes can be used for drug delivery into the body, as lubricants, and as catalysts . They can act as hollow cages to trap other molecules. This is how they can carry drug molecules around the body and deliver them to where they are needed, and trap dangerous substances in the body and remove them.
Is fullerene the pure form of carbon?
Fullerenes are an allotropic form of carbon, consisting of pure carbon atoms. A well-known example is C60, which is shaped like a football, so metal ions and other active agents can be enclosed in the inner cavity. Furthermore, fullerenes themselves can act as a guest molecule in complexes with macrocyclic ligands such as cyclodextrins.
