Aerogel - izolator buducnosti… Wiredov clanak o aerogelu
|
Osim u upotrebi kao odlicni toplinski i zvucni izolatori, moci ce posluziti i kao odlicna skladista energije…
Aerogels are solid substances similar to gels but where the internal liquid is replaced with air. Aerogels rank among the world’s lowest density solids. They are very porous and light, and have remarkably high internal surface area. Their microstructure and physical properties can be manipulated at the nanometer scale by selection of raw material and modification of manufacturing conditions. Aerogel products can be engineered to exhibit desired thermal, acoustic, mechanical and/or chemical properties. Aerogel materials can be produced as monoliths, thin-films, powders, or micro-spheres to respond to given application requirements. |
Slika i tekst najbolje opisuju svojstva toplinske izolacije silikatnog aerogela… “…silica aerogel can protect the human hand from the heat of a blowtorch at point blank range….“
