The Chinese scientist Prof. Gao Chao of Department of Polymer Science and Engineering, Zhejiang University and team invented the world's ever lightest material which might have a good role in pollution control and purification.
It has a mass of 0.16 milligram, according to the Scientists which is less denser than air. The previous record holder is an aerographite. The new material is 12 percent lighter than the previous one. It was made up of graphene which is a lightest compound of carbon.
Aerogel is a low-density solid-state material derived from gel in which the liquid component of the gel has been replaced with gas. The result is an extremely low density solid with several remarkable properties.
It is nicknamed frozen smoke, solid smoke or blue smoke due to its
transparent nature and the way light scatters in the material. (Source)
Aerogels are good thermal insulator also. The original Aerogel formula was invented by Samuel Kistler 7 decades ago and significant development have been made over 2 decades.
It have many applications such as absorbing power which is 900 times to its weight than the other materials. It could absorb oil and other lubricants. It is highly elastic and is a good thermal conductor. “Maybe one day when oil spill occurs, we can scatter them on the sea and absorb the oil quickly,” said Gao. “Due to its elasticity, both the oil absorbed and the aerogel can be recycled.” he mentioned.
