Due to “increasing heat waves around the world,” these textiles could be integrated into clothing, hats and even construction materials, potentially reducing dependence on air conditioning. How? It’s very simple.
Engineers from Zhengzhou University and the University of South Australia described the fabric in the latest issue of Science Bulletin. The textile uses principles of radiative cooling, allowing it to reflect sunlight and radiate heat. Consisting of three layers, the top layer is made of polymethylpentene fibers for effective radiative heat dissipation, the middle layer contains silver nanowires for increased reflectivity, and the bottom layer is made of wool for moisture wicking and comfort.
In the experiments, it was determined that the fabric was 2.3°C cooler than traditional textiles when used vertically and 6.2°C colder than the environment when used horizontally.
Despite the promise, researchers note that current production methods are expensive and require more work.
