In fact, a long time ago, NASA found that white paint can reduce the peak roof temperature by an average of 24°C, but this result is not thorough enough, or extreme.
Now, the latest research result published in the "Joule" magazine shows that the team of UCLA (UCLA) can reflect the solar radiation to a greater extent by adding powdered polytetrafluoroethylene and the like to the traditional white paint. .
Through these changes to the formulation, the cooling ability of an ultra-white coating has been significantly improved, so that it showed that it can reflect up to 98% of incoming radiation during the test. This material can play a big role in reducing the cooling cost of buildings by reducing the use of air conditioners and other systems.
The University of California, Los Angeles (UCLA) team said that deploying it in real-world scenarios should not require much work.
