How does Aerogel density compare to the density of air?
A cubic centimeter of aerogel weighs only 0.16 milligrams, if you’re having trouble conceptualizing that, 1 cubic meter weighs just (5.6 ounces) 160 grams )
Some of the most popular Graphene aerogel properties include the fact that its density is lower than that of helium has and just twice the amount of hydrogen. single square-meter sheet of graphene would weigh just 0.0077 grams
In order to put this information into perspective, You can consider comparing it with regular air. The air you are currently breathing right now normally has 1.2mg/cm3 density, Which is 7 times heavier compared to aerogel.
This makes aerogel lighter than air, and yet it is also a solid.

Graphene Aerogel Synthesis
Aerogel synthesis or production was achieved by expounding on the techniques that were previously used for making 2D Graphene films. This is actually the key behind the fact that Graphene aerogel is lighter than air.is usually comprised of one carbon atoms layer and researchers discovered that Graphene aerogel synthesis could be achieved through using an innovative freeze drying procedure to stack the atoms into 3D.During drying Carbon nanotubes solutions are used And this removes the need to have a template, Which is the case with other aerogels.
Among the main aerogel properties is that its size is determined be the container size in which it was built in. Through this particular technique of Aerogel synthesis, It will be possible to one day produce a huge amount of aerogel. In addition, the nanotubes offer a stabilising benefit for smoother synthesis process.
Graphene Aerogel Applications
Aerogel provides some of the most amazing benefits that may see it being used soon in most industries. For instance, Among the major Aerogel properties is that it is quite elastic and can easily retain its original form after some compression.
Due to the lower density of Graphene aerogel, It is very absorbent, And it can even absorb more than 850 times its own weight. This means when future environmental clean-ups will be required, It will only comprise of spreading Graphene aerogel around the affected area and then it is picked up later after absorbing the organic products like oil.
Beyond these environmental benefits of Aerogel This material may also have some applications in both the storage as well as the transfer of energy. Graphene is actually being studied for high thermal conductivity, And a lot more is expected from this product in the future.
