Aerogel cotton
What is aerogel cotton?
Aerogel is a kind of material with a nanoporous network structure. Aerogel is usually derived from wet gel. The liquid in wet gel is replaced by gas, and the structure that retains the gas-solid multi-empty skeleton without collapse is called aeroge.
Optical property
Nano and multi-space structure is beneficial to infrared absorption, aerogel has strong absorption in far infrared, and can be used for far infrared stealth.
Thermal properties
At the same time inhibit heat conduction, heat convection, heat radiation.
Acoustic performance
As sound waves pass through the aerogel, sound is dissipated, creating the effect of blocking sound waves.
Adsorption property
Aerogel has a large internal surface area, uniform and ordered cavity structure, easy to adsorb other molecular atoms.
The thermal insulation principle of aerogel
Prolong the heat conduction path indefinitely:The mesh skeleton of aerogel extends the path of heat conduction infinitely, which is very difficult. Moreover, the nanoporous structure forms countless gases, and heat is difficult to conduct.
There is no internal air circulation:The pore size of aerogel (20-55nm) is smaller than the mean free path of air (70nm), that is to say, the gas molecules in the pores cannot flow freely, so the heat convection between gas molecules is inhibited.
The gas-solid interface forms numerous thermal partitions:The network skeleton of aerogel forms "infinite thermal diaphragm effect", which has a shielding effect on thermal radiation.
