A team of researchers at Colombia University have recently developed a new reflective polymer coating that can be applied to buildings to keep them cool. The overuse of air conditioners is beginning to take its toll on the environment, but thankfully this new material may be able to replace these units with more efficient cooling properties. Described as snow-like by assistant professor Yuan Yuang, this reflective polymer is filled with micron-sized crystals that creat tiny pockets of air that scatter light.
Capable of reflecting 99% of heat -- when mixed with colored paint -- the material performs best in hot and dry environments. The researchers have theorized that the material could reduce internal temperatures by 10 degrees cooler than the outdoor air.
