Researchers at CityUHK have created an advanced radiative cooling technology, delivering environmentally friendly cooling materials to address climate change.


Researchers at City University of Hong Kong have developed a revolutionary radiative cooling technology that could help combat global warming by providing energy-free cooling materials. This new technology offers a promising solution to reducing energy consumption for cooling purposes, particularly in hot and tropical regions.

The breakthrough technology, known as radiative cooling, works by reflecting sunlight and radiating heat back into space, effectively cooling the surrounding area without the need for any electricity or other energy sources. This method offers a more sustainable and cost-effective cooling solution compared to traditional methods, such as air conditioning, which can be energy-intensive and contribute to greenhouse gas emissions.

The CityUHK researchers have successfully created a specialized polymer film that can be applied to various surfaces, such as roofs and walls, to provide passive cooling effects. The film is able to reflect up to 96% of sunlight and radiate heat away from the surface, resulting in a significant reduction in temperature. This technology has the potential to greatly reduce the energy consumption associated with cooling buildings and vehicles, making it a valuable tool in the fight against climate change.

With global warming becoming an increasingly urgent issue, innovations like this radiative cooling technology are crucial for finding sustainable solutions to reduce carbon emissions and mitigate the impacts of climate change. The CityUHK researchers are continuing to refine and optimize their technology, with the hope of bringing it to market in the near future.

Overall, this groundbreaking research from City University of Hong Kong has the potential to revolutionize the way we approach cooling technologies and make a significant impact in the fight against global warming. By providing energy-free cooling materials, this technology offers a promising pathway towards a more sustainable and environmentally-friendly future.
