The lightest solid component on earth has shredded even more weight. The frozen smoke is surprisingly 95 to 97 percent just air. And is being seen as the future key component in the automobile industry.
Frozen Smoke – the lightest solid material in the world with a density of 4mg/cm3 justifies its name pretty well. It takes only 0.5-gram of this material to cover an area of 250 meters.
- Researchers have developed a new aerogel with formidable strength and an amazingly large surface area, nicknamed frozen smoke,
- Aerogels are solid materials of extremely low density. These materials are nothing but a matter with no solvent and largely constituted by some gas.
- They are generally derived by removing the liquid components from convention gel. The liquid component of these aerogels is replaced with a gas which makes them super light.
- The new lightweight is named multiwalled carbon nanotube aerogel(MWCNT).
- The researchers are now planning to use it in sensors to detect pollutants and toxic substances, chemical reactors, and electronic components.
- What makes this aerogel even more special is that very few scientists have been successful in making aerogels from carbon nanotubes rather than silica, metal oxides, polymers, and carbon-based materials.
- The researchers were able to succeed where so many before them had failed using a wet gel of well-dispersed pristine MWCNTs.
- After removing the liquid component from the MWCNT wet gel, they were able to create the lightest ever free-standing MWCNT aerogel monolith with a density of 4 mg/cm3.
- Additionally, MWCNT aerogels infused with a plastic material are flexible, like a spring that can be stretched thousands of times.
- The MWCNT aerogels are also excellent conductors of electricity. This is what makes them ideal for sensing applications. Therefore, it offers great potential for their use in electronics components.
