Aerogel, a masterpiece at the forefront of science and technology, has become a typical super material . It occupies a unique position in the field of materials science with its unparalleled properties such as high efficiency, energy saving , heat insulation, waterproofing, and long life .

In particular, it has an exquisite nano-porous network structure. This structure is like a microscopic maze where nature and human wisdom intertwine. The pores are small, even smaller than a hair , but they are spread throughout the entire material system, forming countless tiny And intricate passages.

Get closer to the mysterious aerogel

Aerogel was invented by Americans in 1931 and gradually became industrialized in the 1980s . Its low thermal conductivity, high fire resistance, good waterproofing effect, and long service life completely outperform traditional insulation materials.

First, airgel has low thermal conductivity. Because aerogel has a porous structure, this structure greatly limits the heat conduction path, causing heat to encounter many obstacles when transferring inside the material, resulting in an extremely low thermal conductivity, which is much lower than traditional insulation materials such as glass fiber and rock wool. According to laboratory data, the thermal conductivity of airgel can reach an astonishing range of less than 16mW/mK , which is comparable to the star among thermally conductive materials.

Secondly, aerogel has a high fire resistance rating. Airgel contains high-temperature resistant components such as inorganic or polymeric silicone, and has good fire resistance. Its fire rating usually reaches Class A (non-combustible material) standards.

Again, the gel is very waterproof. The nanoporous structure of airgel can effectively prevent moisture penetration. At the same time, airgel products can be specially treated to make their surface more hydrophobic, further improving the waterproof effect. This characteristic allows aerogels to maintain good thermal insulation properties in humid or underwater environments, while traditional thermal insulation materials tend to have significantly reduced performance when exposed to water.

Fourth, airgel has a long service life. The extremely stable chemical properties and physical structure of airgel ensure that its thermal insulation performance will not significantly decrease over time under normal use conditions, and it can maintain efficient thermal insulation effect for a long time. However, traditional thermal insulation materials may suffer performance degradation due to aging, corrosion and other reasons during use, and need to be replaced regularly. In terms of economic costs, aerogel also beats traditional materials.

Due to its powerful properties, aerogels are widely used in petrochemical industry, thermal pipe network, lithium batteries, construction materials, outdoor clothing, aerospace, military industry and other fields . Especially in today's carbon neutral era, energy conservation and emission reduction have become Trends, new material aerogel will undoubtedly become a hot spot in the industry.
