Columbia engineers built a pigment-free polymer coating filled with microscopic air pores; under Arizona desert sun, the coated surface stayed about 6°C below ambient air
- Porous polymer coating reflects sunlight and releases heat, keeping surfaces cooler than the airAs temperatures rise during hot weather, keeping buildings and other structures cool can require large amounts of energy.
- Air conditioners are a common way to deal with the heat, but they consume electricity and need access to cooling systems and, in some cases, coolants that can affect the environment.
- Researchers at Columbia Engineering have created a polymer coating that can be applied like paint and uses microscopic air voids instead of white pigments.
