Aerogels: Latest generation materials with great isothermal insulating power

Aerogels: Latest generation materials with great isothermal insulating power

The containment of liquids at very low temperatures

With their excellent insulating properties, aerogels also play an important role in the storage of cryogenic liquids. These are cryogenic fluids, meaning they have to be stored very cold: hydrogen at -253°C (-423°F) and oxygen at -183°C (-297°F) so that they remain liquid. Recently proposed aerogel formulations offer capabilities not only to be formed into cylinders and trapezoids for the transfer and storage of cryogenic liquids, but also to be made resistant to environmental corrosion.8

There are many other applications of aerogels in space exploration, including fire-resistant space suits that provide insulation from the extreme environment and aerocondensers that would use the surface area of ​​carbon aerogels to improve storage devices. energy.9

This technology is not limited to space applications, but is also beginning to be used in building insulation and outdoor clothing. Now, you can buy a chic airgel jacket for $300! Recently, OROS operated a campaign

from Kickstarter to support aerogel things including jackets, gloves and snow pants, insulated bags.

Scientists around the world are working to improve the properties of aerogels. They are using different materials and compositions to form stronger, more flexible and lighter aerogels. Although high production costs still limit the development of aerogel technology, there is no doubt that these incredible materials with amazing properties will soon become more widely available in a product that will be using you.
