Graphene Aerogel
Composite Material: A combination of 2 materials with wonderful properties to produce a supermaterial with extensive properties
Aerogel
Graphene
Aeorgels are composed of small amounts of solid particles in a liquid supension. When the liquid is replaced with air, the air is trapped within very tight pockets, captured within the networks formed by the remaining solid material. The composition of an Aeorogel is purely air and solid particles, making them a solid that is just slightly heavier than air.
Graphene is an allotrope originated from a type of bonding combination of different carbon atoms as carbon has four valence electrons. Graphene has a similar structural strength to Diamond but it is a 2-D material being only one carbon atom thick and it is the strongest material known today.
Aerographene
Graphene on its own is a material with high strength, however when combined with multiple sheets of graphene, it is not as strong. Nontheless, if the sheets of graphene are separated by air-filled pores, it becomes graphene aerogel which is well over 99% air by weight.
Aerographene is the least dense solid in existence and it is light enough to be balanced on small plants. It is elastic and can retain its orginial form after compression and also has a very low density that allows it to absorb more than 850 times its own weight. These properties enable the aerogel to be used for environmental clean-ups (adsorption of oil and organic polllutants), batteries, supercapacitors and electrochemical sensors
Uses of Aerographene
A potential use of aerographene is in batteries, especially lithium-based batteries. Its capacity to absorb large amounts of liquid allows it to be used as a 'catholyte' solution that interacts with the battery's lithium anode. Li-S batteries have the potential to store between 1 and 1.5 kwh/kg of battery weight, far more than the 0.35 kwh limit on current Li-ion batteries. Other applications include aerographene being used to manufacture supercapacitors with high enerrgy densities.
Aerographene can be used to purify/desalinate water under simulated light. This process is done by graphene aerogel concentrating the sunlight and heating up the water to 45C, the porous structure pumps steam away from the surface and this steam is free from pollutants
