Surface coating with high solar reflectance and high thermal emittance are attractive for saving energy in buildings. Conventional paints typically have a solar reflactance < 93% due to UV and near infrared absorption. Here we demonstrate a porous PVdF copolymer surface coating that shows high solar reflectance of over 96% and high thermal emittance of 0.97. When it is placed under sunlight, it can be 6 oC cooler than the environment without any electricity.
