At the time, researchers went as far as to say that their white paint was the closest thing available to an equivalent of "Vantablack," which absorbs up to 99.9% of visible light . The whitest white barn roof was also much cooler to the touch, prompting many surprised responses from judges and viewers. Ranked in each of the last five years as one of the 10 Most Innovative universities in the United States by U.S. News & World Report, Purdue delivers world-changing research and out-of-this-world discovery. by Purdue University. See how Purdue never stops in the persistent pursuit of the next giant leap athttps://purdue.edu/. Purdue University is a top public research institution developing practical solutions to todays toughest challenges. Two features make this paint ultra-white, according to Purdue University: a very high concentration of a chemical compound called barium sulfate also used in photo paper and cosmetics and different particle sizes of barium sulfate in the paint, scientists at Purdue said. This new paint achieves nearly the same benchmark of solar reflectance (97.9%) with just a single 150-micron layer of paint. The newer paint not only is whiter but also can keep surfaces cooler than the formulation that the researchers had previously demonstrated. (Purdue University/Joseph Peoples), for this paint formulation have been filed through the, Purdue Research Foundation Office of Technology Commercialization, An equal access/equal opportunity university, Maintained by Office of Strategic Communications. Trouble with this page? Now, the blackest black color has met its match in the whitest white, which was created this year by researchers at Purdue University. Thats more powerful than the central air conditioners used by most houses, said Xiulin Ruan, a Purdue professor of mechanical engineering. (Along the way, they also developed an earlier ultra-white paint made from calcium carbonate that reflected 95.5 percent of sunlight.). More specifically, Im curious as to when it will be available so I can use on my kitchen walls! The record appears in the 2022 edition of Guinness World Records, available for purchase starting Thursday (Sept. 16). Committed to hands-on and online, real-world learning, Purdue offers a transformative education to all. Scientists created the world's whitest paint. The ultra-white paint was engineered with a very high percentage of barium sulfate, a chemical compound with particles of varying sizes that allow the paint to scatter more light.
