The whitest paint is here – and it’s the coolest. Literally.
2021年4月15日 — In an effort to curb global warming, Purdue University engineers have created the whitest paint yet. Coating buildings with this paint may one day cool them off enough to reduce the need for air conditioning, the researchers say.
The whitest paint is here – and it’s the coolest. Literally.
2021年4月15日 — The new whitest paint formulation reflects up to 98.1% of sunlight – compared with the 95.5% of sunlight reflected by the researchers’ previous ultra-white paint – and sends infrared heat away from a surface at the same time.
World’s whitest paint now thinner than ever, ideal for vehicles
2022年10月3日 — Purdue University researchers have created a new formula for the world’s whitest paint, making it thinner and lighter. The previous iteration (left) required a layer 0.4 millimeters thick to achieve sub-ambient radiant cooling.
To Help Cool a Hot Planet, the Whitest of White Coats
2023年7月12日 — Scientists at Purdue have created a white paint that, when applied, can reduce the surface temperature on a roof and cool the building beneath it.
Is Climate-Cooling Paint Coming to a Hardware Store Near You?
2023年7月20日 — Purdue University researchers are starting to get the world’s whitest white paint out of engineering labs and onto the market for commercial use.
Purdue’s ‘world’s whitest paint’ wins 2023 SXSW Innovation Award
2023年3月14日 — The world’s whitest paint, developed by Purdue University researchers and recognized in Guinness World Records, has been named winner of the 2023 Innovation Award in the sustainability category by South by Southwest Conference & Festivals (SXSW).
Scientists Have Developed the Whitest White Paint Ever …
