 
- Summary
- Radiative cooling paints to be used to facilitate reflecting solar radiation away from a surface and dissipating heat by thermal radiation to achieve cooling effect
- Technology Benefits
- Radiative cooling paints can provide cooling effect passively
- Technology Application
- Painting on buldings, automobiles, roads, curtains and outdoor electronics; Thermal management of solar cells;Self-cooling merchandise by coating radiativce cooling paint on the outer layer of umbrellas/hats/textiles
- Detailed Technology Description
- The radiative cooling paint , an emerging applied Nano-material technology that can block the incoming solar irradiance from the sun, while simultaneously creating a cooling effect by emitting thermal radiation to the cold universe (~-270 °C). Hence, sub-ambient cooling can be achieved even under direct sunlight. Different from conventional cooling technologies, the radiative cooling paint leads the way to eco-friendly and energy-free cooling without causing ozone depletion and greenhouse effect. Based on the results of our radiative cooling paint, by applying this cooling technology on a building rooftop, the rooftop temperature can be reduced by 15 ⁰C under direct sunlight when it is compared to the rooftop without coating the PRCP, saving about 10% of cooling energy of traditional air-conditioning systems in buildings
