Polymer coating cools down buildings

September 27, 2018

Columbia University Engineers have invented a high-performance exterior passive daytime radiative cooling polymer coating with nano-to-microscale air voids that acts as a spontaneous air cooler and can be fabricated, dyed and applied like paint on rooftops, buildings, water tanks, vehicles, even spacecraft -- anything that can be painted. They used a solution-based, phase-inversion technique that gives the polymer a porous foam-like structure. Full Story
