Aerogel materials magic to change the world
According to the British "Times" reported on August 19, aerogels called one of the world's lightest solid, but the magic was able to withstand 1000 kg of solid explosive blast, but also cut off 1300 degrees Celsius temperature. Scientists are developing a variety of new uses of this material from a new generation of tennis rackets to help humans to Mars super insulation space suit. Scientists believe that aerogels will change the world of materials.
Bet bet out of the invention
Aerogels of the invention by accident --- 1931 an American chemist and colleague bet --- the product of the water will take down the ordinary silica, carbon dioxide and then inject this gas, resulting in a dreamlike the solid. Although aerogels were classified as solid, but 99% of the substances are gases. Thus, the outside world gave it a "frozen smoke," the nickname.
This magic with high-temperature solid and oil absorption characteristics of the fragile aerogels early and expensive, so lock in the test room when the display.
Until 10 years ago, NASA began to feel "kept in purdah did not know," the material had a strong interest, began to explore the more practical use: in 1999, NASA used its full of "starburst" space detectors, and by its strong adsorption to capture tail material, results with great success: last year, carrying tail material rewarding experience.
Wide range of future applications
Aerogel is the best insulation materials, extreme temperatures can be isolated. In 2002, NASA created the company Aspen Aerogel produced a greater tolerance and flexibility of the aerogels. It is now being used to make a space suit thermal insulation lining, so as 2018 to prepare for human landing on Mars.
Aerogel also for environmental protection purposes. Some scientists call it "the best sponge" because of its numerous holes on the surface of the absorption of water contaminants is the best.
In daily life, aerogels are also a variety of purposes. Dunlop sports equipment company has developed a range of materials using Aerogel squash and tennis rackets, said that this can enhance the strength of hitting. Aerogel is also widely used in house insulation, hiking shoes, and other places. In the future, it will be more widely used.
