Aerogel is also known as dry gel, using the sol-gel method, through a certain drying method to change the liquid phase of the gel into a gas and formed a nanoscale porous solid material, its interior is a nanoscale three-dimensional network structure, you can also understand as a nanoscale porous sponge. Aerogel has the characteristics of high porosity, low density, light weight, low thermal conductivity, heat insulation and so on.
Aerogel can be combined with pre-oxygenated silk, ceramic fiber and glass fiber to form composite materials, and these three composite materials determine the degree of fire protection up to 400-1000℃. In addition, aerogel can not only heat insulation, but also has a good hydrophobicity, hydrophobicity of 97%, is a material that can simultaneously have fire, waterproof, heat insulation and other needs.
In fact, aerogel is not a newly developed material, before this has been applied to oil pipeline insulation and military aerospace and other fields, and commercial can not be widely used the main technology is monopolized by the West, the price is more expensive.
With the continuous research and development of aerogel and the continuous improvement of the production process, coupled with the official release of the "Opinions of the Central Committee of the Communist Party of China and The State Council on the complete, accurate and Comprehensive implementation of the new development Concept to do a good job of carbon Peak carbon neutrality" (Zhongfa [2021] No. 36), aerogel has gradually become commercialized and recognized by more people.

According to relevant data, in 2021, the amount of aerogel in the oil and gas field is very large, with a proportion of 56%, the amount of industrial insulation is 18%, the amount of building construction is 9%, and the amount of transportation is 8%. According to industry-related data, aerogel materials will be widely used in new energy vehicles and energy storage industries in the future, and the compound annual growth rate of segmented industries in the next 3-5 years will be as high as 150% to 200%.

Aerogel is not only used in oil pipeline insulation and military aerospace and other high-end fields, but also can be used in green energy-saving buildings, new infrastructure, clothing, new energy vehicles and other cold insulation, fire prevention, waterproof, noise reduction and other related fields. As an excellent thermal insulation material, aerogel has attracted much attention in the market.
