As far back as the 1970s, scientists and manufacturers had been developing whiter and whiter paints to help reflect sunlight and keep buildings and other surfaces cool. However, the whitest paints available on the market today reflect 90% of light\u2014a number that sounds high but means they still absorb 10% of sunlight and so cannot cool a surface below the ambient temperature.<\/p>\n<p class=\"sc-77igqf-0 bOfvBY\">In 2014, a group from Stanford <span><a class=\"sc-1out364-0 hMndXN sc-145m8ut-0 cFSTdr js_link\" data-ga=\"[[&quot;Embedded Url&quot;,&quot;External link&quot;,&quot;https:\/\/web.stanford.edu\/group\/fan\/publication\/Raman_Nature_515_540_2014.pdf&quot;,{&quot;metric25&quot;:1}]]\" href=\"https:\/\/web.stanford.edu\/group\/fan\/publication\/Raman_Nature_515_540_2014.pdf\" target=\"_blank\" rel=\"noopener noreferrer\">wrote a paper<\/a><\/span> on using layers of reflective surfaces of inorganic compounds to reflect sunlight and cool surfaces below the ambient temperature during the day, a process that, while effective, was expensive and not scalable. Purdue University engineering professor Xiulin Ruan, inspired by the Stanford work, started to wonder about the further practical applications of nanotechnology in working with paints, specifically to combat climate change.<\/p>\n<div class=\"sc-17kx9cd-5 enWAiR js_ad-mobile-dynamic js_ad-dynamic ad-mobile-dynamic movable-ad\">\n<div class=\"sc-17kx9cd-4 grZkjw ad-unit ad-mobile\">\n<div class=\"sc-17kx9cd-0 gJTWjl\">Advertisement<\/div>\n<\/div>\n<\/div>\n<p class=\"sc-77igqf-0 bOfvBY\">\u201cWe were not really thinking about developing the <em>whitest<\/em> paint,\u201d Ruan said. \u201cMy background is as a civil engineer and researcher, so I care about that heat.

It was so effective that they quickly outpaced their own record, and in 2021 created a paint that reflects 98.1% of sunlight.

The paint was also not very viscous: The barium sulfate paint was formulated as a gel for maximum effectiveness, which makes it difficult to apply to surfaces that are not buildings or structures.<\/p>\n<div class=\"sc-17kx9cd-5 enWAiR js_ad-mobile-dynamic js_ad-dynamic ad-mobile-dynamic movable-ad\">\n<div class=\"sc-17kx9cd-4 grZkjw ad-unit ad-mobile\">\n<div class=\"sc-17kx9cd-0 gJTWjl\">Advertisement<\/div>\n<\/div>\n<\/div>\n<p class=\"sc-77igqf-0 bOfvBY\">\u201cIt\u2019s not easy to make paint paintable, sprayable, or brushable,\u201d said Ruan.<\/p>\n<p class=\"sc-77igqf-0 bOfvBY\">He tapped his Purdue colleague George Chiu, who has a background in photonics and digital printing, as well as two PhD students, Andrea Felicelli and Ioanna Katsamba, to figure out a way to keep the light-reflecting properties of barium sulfate without the extra baggage the compound adds.<\/p>\n<div class=\"sc-17kx9cd-5 enWAiR js_ad-mobile-dynamic js_ad-dynamic ad-mobile-dynamic movable-ad\">\n<div class=\"sc-17kx9cd-4 grZkjw ad-unit ad-mobile\">\n<div class=\"sc-17kx9cd-0 gJTWjl\">Advertisement<\/div>\n<\/div>\n<\/div>\n<figure class=\"sc-1eow4w5-1 eLNveM align--bleed js_lazy-image js_marquee-assetfigure\" data-id=\"79befe81f85cd1b757aa00afddc514d1\" data-recommend-id=\"image:\/\/79befe81f85cd1b757aa00afddc514d1\" data-format=\"jpg\" data-width=\"3840\" data-height=\"2160\" data-lightbox=\"true\" data-recommended=\"false\" data-hide=\"false\">\n<div class=\"sc-1eow4w5-2 loxZOX has-data img-wrapper\" data-link-reference=\"\" data-link-target=\"\" data-syndicationrights=\"false\" data-imagerights=\"other-license\" data-hide=\"false\" data-hidecredit=\"false\"><span class=\"sc-1eow4w5-0 dnhHtZ js_lightbox-wrapper\"><\/p>\n<div class=\"sc-1eow4w5-3 lktKQM image-hydration-wrapper\"><img decoding=\"async\" src=\"image\/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==\" alt=\"Ruan, Felicelli, Katsamba and Chiu look at paint samples in the lab.\" data-chomp-id=\"79befe81f85cd1b757aa00afddc514d1\" data-format=\"jpg\" data-alt=\"Ruan, Felicelli, Katsamba and Chiu look at paint samples in the lab.\" data-anim-src=\"\" \/><\/div>\n<p><\/span><\/div>\n<p><span data-id=\"79befe81f85cd1b757aa00afddc514d1\" data-recommend-id=\"image:\/\/79befe81f85cd1b757aa00afddc514d1\" data-format=\"jpg\" data-width=\"3840\" data-height=\"2160\" data-lightbox=\"true\" data-recommended=\"false\" data-hide=\"false\" class=\"js_recommend\"><\/span><\/figure>\n<p class=\"sc-77igqf-0 bOfvBY\">\u201cBarium sulfate has reflective properties that allow us to hold below ambient temperature,\u201d said Felicelli, whose research focuses on bioinspired nanocomposites. \u201cBut it also contributes a lot to the weight of the paint.\u201d<\/p>\n<div class=\"sc-17kx9cd-5 enWAiR js_ad-mobile-dynamic js_ad-dynamic ad-mobile-dynamic movable-ad\">\n<div class=\"sc-17kx9cd-4 grZkjw ad-unit ad-mobile\">\n<div class=\"sc-17kx9cd-0 gJTWjl\">Advertisement<\/div>\n<\/div>\n<\/div>\n<p class=\"sc-77igqf-0 bOfvBY\">They began looking at different materials to use in a new formulation of the paint. They eventually settled on hexagonal boron nitride, an inorganic compound mostly used in lubricants. Not a lot of literature had been written around how particle shape helps reflect sunlight, and Katsamba was tasked with modeling how boron nitride helped make the paint reflective\u2014a topic that hadn\u2019t really been addressed before. Boron nitride has a unique morphology, called nanoplatelets, that proved to help it repel sunlight more effectively than spherical particles in other compounds. <\/p>\n<p class=\"sc-77igqf-0 bOfvBY\">\u201cThe simulations show that it\u2019s not only the properties of boron nitride, which are different from barium sulfate, but also the shape that really helps on achieving that higher reflectivity we have now,\u201d Katsamba said.<\/p>\n<div class=\"sc-17kx9cd-5 enWAiR js_ad-mobile-dynamic js_ad-dynamic ad-mobile-dynamic movable-ad\">\n<div class=\"sc-17kx9cd-4 grZkjw ad-unit ad-mobile\">\n<div class=\"sc-17kx9cd-0 gJTWjl\">Advertisement<\/div>\n<\/div>\n<\/div>\n<p class=\"sc-77igqf-0 bOfvBY\">Even after settling on a compound that models showed would be great at reflecting sunlight, making the paint itself was still a challenge\u2014especially given that boron nitride\u2019s morphology made some of the paints thicker and less viscous.<\/p>\n<p class=\"sc-77igqf-0 bOfvBY\">\u201cWe definitely had some issues getting the particles to incorporate fully into the paint mixture,\u201d Felicelli said. \u201cBut over time, we were able to resolve those different processing techniques. And we were able to achieve an application that was very similar to your regular commercial white paint.\u201d<\/p>\n<div class=\"sc-17kx9cd-5 enWAiR js_ad-mobile-dynamic js_ad-dynamic ad-mobile-dynamic movable-ad\">\n<div class=\"sc-17kx9cd-4 grZkjw ad-unit ad-mobile\">\n<div class=\"sc-17kx9cd-0 gJTWjl\">Advertisement<\/div>\n<\/div>\n<\/div>\n<p class=\"sc-77igqf-0 bOfvBY\">The resulting paint using boron nitride is nearly as effective as the first formulation with barium sulfate: It can reflect up to 97.9% of sunlight. What\u2019s more, it only requires a 0.15 millimeter layer to be effective, and, thanks to the compound\u2019s porous structure that incorporates a lot of air, weighs 80% less than the barium sulfate paint.<\/p>\n<p class=\"sc-77igqf-0 bOfvBY\">While you can\u2019t go out and buy this ultra-white paint right now, Ruan said the team is in talks with manufacturers to begin the process of creating and selling it as a product. The paint is also being perfected and tested to ensure it can resist dirt and can last as long under UV light as commercial white paints. Down the road, Ruan said, he\u2019s also interested in creating reflective paint in different colors, as well as paints that could switch from reflective to absorptive, depending on the season\u2014like a building-size version of drinkware that changes color when you pour hot or cold water into it.<\/p>\n<div class=\"sc-17kx9cd-5 enWAiR js_ad-mobile-dynamic js_ad-dynamic ad-mobile-dynamic movable-ad\">\n<div class=\"sc-17kx9cd-4 grZkjw ad-unit ad-mobile\">\n<div class=\"sc-17kx9cd-0 gJTWjl\">Advertisement<\/div>\n<\/div>\n<\/div>\n<p class=\"sc-77igqf-0 bOfvBY\">\u201cRight now, the paint is for cooling, so it\u2019s great for hot climates,\u201d he said. \u201cBut in Indiana, for example, we need heat in the winter. It would be great if you were able to switch from the whitest paint in the summer to a color that can absorb sunlight. That is challenging to make it cost effective, to make it scalable. We are investigating, and we can\u2019t expose all the details now, but we can learn from nature to help us understand how to make those kinds of technologies possible.\u201d<\/p>\n<p class=\"sc-77igqf-0 bOfvBY\">Read more: <span><a class=\"sc-1out364-0 hMndXN sc-145m8ut-0 cFSTdr js_link\" data-ga=\"[[&quot;Embedded Url&quot;,&quot;Internal link&quot;,&quot;https:\/\/gizmodo.com\/whitest-paint-reflects-light-cools-buildings-nanotech-1850108248&quot;,{&quot;metric25&quot;:1}]]\" href=\"https:\/\/gizmodo.com\/whitest-paint-reflects-light-cools-buildings-nanotech-1850108248\">The World\u2019s Whitest Paint Is Literally the Coolest<\/a><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>It\u2019s common sense: When it\u2019s hot outside, don\u2019t put on a dark shirt\u2014wear white instead.<\/p>\n","protected":false},"author":1,"featured_media":42586,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"_links":{"self":[{"href":"https:\/\/peymantaeidi.net\/stem-cell\/wp-json\/wp\/v2\/posts\/42588"}],"collection":[{"href":"https:\/\/peymantaeidi.net\/stem-cell\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/peymantaeidi.net\/stem-cell\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/peymantaeidi.net\/stem-cell\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/peymantaeidi.net\/stem-cell\/wp-json\/wp\/v2\/comments?post=42588"}],"version-history":[{"count":2,"href":"https:\/\/peymantaeidi.net\/stem-cell\/wp-json\/wp\/v2\/posts\/42588\/revisions"}],"predecessor-version":[{"id":42590,"href":"https:\/\/peymantaeidi.net\/stem-cell\/wp-json\/wp\/v2\/posts\/42588\/revisions\/42590"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/peymantaeidi.net\/stem-cell\/wp-json\/wp\/v2\/media\/42586"}],"wp:attachment":[{"href":"https:\/\/peymantaeidi.net\/stem-cell\/wp-json\/wp\/v2\/media?parent=42588"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/peymantaeidi.net\/stem-cell\/wp-json\/wp\/v2\/categories?post=42588"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/peymantaeidi.net\/stem-cell\/wp-json\/wp\/v2\/tags?post=42588"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
