Aerogel is a good insulation material, but why can't it be made into clothes?

Aerogel is a porous material with no mechanical properties. If it is to be used in clothing, it is necessary to stick aerogel powder together with adhesive to make sheets with mechanical properties. However, the particle size of the binder is much smaller than the pore size of aerogel. When aerogel powder is added to liquid, the adhesive polymer material fills the pores of aerogel, and aerogel loses the ability of porous materials to store air and insulate heat.

But it can be made into textiles, warm clothes or navy diving suits, spacesuits and so on.

Other uses:

1, bulletproof and not afraid of being bombed

Bulletproof is the second important use of new aerogels. NASA is testing houses and military vehicles built with aerogels. According to the laboratory test, if a layer of aerogel with a thickness of about 6 mm is added to the metal sheet, even if the explosive is blown directly, it will not hurt the metal sheet.

2. Be able to cope with ecological disasters

Environmental protection is the third important function of new aerogels. Scientists affectionately call aerogel "super sponge" because it has millions of small holes on its surface, so it is an ideal material to absorb pollutants in water.

The aerogels newly invented by American scientists can actually absorb lead and mercury from water. According to the scientist, this kind of aerogel is an excellent material to deal with ecological disasters. For example, 72,000 tons of crude oil leaked after the sinking of 1996 "Haikuai" oil tanker. If this material had been used at that time, it would not have caused serious pollution to the whole coast.

3. Tennis racket has better hitting ability.

In the future, new aerogels will also enter our daily life. For example, Deng Lupu Sports Equipment Company has successfully developed tennis rackets containing aerogels.
