Aerogel remarkable properties

How do you understand aerogel?
In simple terms, a gel, like a jelly, when you use supercritical drying technology to dry out the liquid components in the jelly, what you see is a spatial network structure filled with air, and yes, that structure is an aerogel.
Nowadays, there are many kinds of aerogels, such as silicon, carbon, sulfur, metal oxide, metal and so on.
aerogel is a combinatorial word, where aero is an adjective meaning 'in the air'. gel is obviously a gel. It literally means air gel. gel of any substance can be called aerogel as long as it can be dried to remove the internal solvent, and can basically keep its shape unchanged, and the product has high porosity and low density.
At present, the product forms of aerogel are mainly: felt, plate, film, cloth, paper, fiber, particle, powder and shaped parts.
It is well known that aerogel has excellent physical and chemical properties such as high porosity, high specific surface area, low density and good adiabatic performance.

A large piece rests easily on the flower's core, which is soft and barely deformed.

Put the aerogel under the delicate flowers, even if it is baked in the fire, the flowers are still intact, and even want to slowly bloom, the heat insulation performance can be seen! In addition, aerogels have important application prospects in aerospace, catalysis, applied construction, environmental remediation, industry and other fields.
However, it's only in the last few years that aerogel has really gained fame, because it can actually be used to make clothes! As the preferred material of NASA space suits, the special network porosity structure makes its heat insulation a unique feature.
Under the huge halo of the space suit, the shining debut of the civilian textile application of aerogel is very amazing.
