World’s whitest paint prevents global warming


Scientists at Purdue University prevent global warming so far developed for the whitest paint designed. Coating buildings with this paint, researchers said. will reduce the need for air conditioning He said he could cool it down.

The same research team pushed the boundaries in October an ultra white paint had developed. Now, scientists who go beyond this are not just a white paint; it also demonstrated a work that could keep surfaces cooler.

This ‘white’ will be an alternative weapon against global warming

Xiulin Ruan, a professor of mechanical engineering at Purdue University, said in the study on the world’s whitest paint:

We estimate that if you use this paint to cover a roof area of ​​about 300 square meters, you can achieve 10 kilowatts of cooling power. These proportions are stronger than central air conditioners used by most homes.

The whitest paint in the world

The resulting white is the blackest, absorbing 99.9 percent of visible light, the researchers said.VantablackHe believes it is equivalent to ”. The latest white paint formulation reflects 98.1 percent of light, compared to 95.5 percent sunlight reflected by the researchers’ previous ultra white paint. That’s why scientists see the white in question as a good weapon against global warming.

The main element that makes the tone so white as a result of the studies is a very high chemical compound called barium sulphate, which is also used to make photographic paper and cosmetic products white.

Another important feature is that the barium sulphate particles in the paint are all in different sizes. The way each particle scatters as much light varies according to its size. So a wider range of particle sizes allows the paint to scatter more of the light spectrum from the sun.
