What is Aerogel Sheet?
Aerogel is a truly fascinating material that has gained attention for its extraordinary insulation properties. Often called “frozen smoke,” aerogels are formed through a process that replaces the liquid in a gel with gas, resulting in a solid structure comprised mostly of air. Aerogel sheets, blankets, and films are popular forms of this material, each designed to meet specific thermal management needs in a variety of applications.
The chemical composition of aerogel generally consists of silica, though it may also include alumina and various polymers, depending on the desired properties. The microstructure of aerogels is characterized by their nanoporous nature, with pores as small as 20 nanometers. This unique structure allows aerogels to achieve extremely low thermal conductivities ranging from 0.017 to 0.035 W/m·K. With a density often as low as 1 kg/m³, aerogels stand as some of the lightest materials known, making them highly effective for insulation in diverse environments.
