Researchers at the University of Chicago’s Pritzker School of Molecular Engineering have developed a new wearable cooling fabric that reduces heat from the sun and thermal radiation from buildings, cars, and pavements. This fabric can keep temperatures up to 2.3°C cooler than current sportswear and up to 8.9°C cooler than silk clothing. 

It provides a passive cooling system, reducing reliance on air conditioning: tested in Arizona and Chicago, the fabric can be used for clothing, building materials, and food storage, potentially lowering internal temperatures and preventing spoilage. 

The fabric, which has a provisional patent, aims to mitigate heat-related health issues during heat waves.
