Aerogels may be used to separate oil from water, which could for example be used to respond to oil spills. [103] [80] [75] Aerogels may be used to disinfect water, killing bacteria. [104] [105] Aerogel can introduce disorder into superfluid helium-3. [106] In aircraft de-icing, a new proposal uses a carbon nanotube aerogel. A thin filament is ...
Aerogel is a low-density solid-state material derived from gel in which the liquid component of the gel has been replaced with gas. The result is an extremely low density solid with several remarkable properties, most notably its effectiveness as a thermal insulator. It is also very strong structurally, able to hold over 2000 times its own weight.
Graphene aerogels have a Young's modulus on the order of 50 MPa. [7] They can be compressed elastically to strain values >50%. [6] The stiffness and compressibility of graphene aerogels can be attributed in part to the strong sp 2 bonding of graphene and the π-π interaction between carbon sheets.
Boron nitride aerogel is an aerogel made of highly porous boron nitride (BN). It typically consists of a mixture of deformed boron nitride nanotubes and nanosheets . It can have a density as low as 0.6 mg/cm 3 and a specific surface area as high as 1050 m 2 /g, and therefore has potential applications as an absorbent , catalyst support and gas ...
They include silica aerogels, carbon nanotube aerogels, aero graphite, metallic foams, polymeric foams, and metallic micro lattices. [1] Ultralight materials are produced to have the strength of bulk-scaled properties at a micro-size. Also, they are designed to not compress even under extreme pressure, which show that they are stiff and strong. [2]

In 2002, aerogel held the Guinness World Record for the least dense (lightest) solid. [16] Aerogel is mostly air because its structure is like that of a highly vacuous sponge. The lightness and low density is due primarily to the large proportion of air within the solid and not the silicon construction materials. [17]
