Kaust<\/strong>researchers develop eco-friendly cooling film: <\/strong>Researchers from King Abdullah University of Science and Technology (Kaust) have developed a novel passive cooling technique that uses a superabsorbent polymer film to lower temperatures without the use of any electricity, according to a statement<\/a>. The team \u2014 who published their findings (pdf)<\/a> in Nature Communications Journal \u2014 is currently designing a simplified device to produce the film at an industrial scale.<\/p>\n

Why does it matter?<\/strong> The researchers demonstrated that the film can reduce the temperature by 5 \u00b0C under a partly cloudy sky, potentially saving up to 3.3% of the total energy consumption for cooling if used on a commercial scale. <\/p>\n

How does it work?<\/strong> The film is made from sodium polyacrylate<\/a>, a material commonly used in diapers, hair gels, and soaps due to its ability to absorb and retain water. Kaust\u2019s super-absorbent polymer can collect moisture from the air at night and release it during the day for evaporative cooling<\/a>, lowering the temperature by using the evaporated water to cool hot air. The material also has high thermal emissivity and reflectivity properties to allow for radiative cooling<\/a> \u2014 a process that involves the emission of infrared thermal radiation from a surface to its surroundings (including the atmosphere and outer space), to cool down its temperature. <\/p>\n

Lots of potential energy applications ahead: <\/strong>The team is now working on scaling up the production and exploring applications for the film, such as cooling solar panels, light-emitting diodes (semiconductors that act as a one-way switch for current), and batteries. The research team is using a lab-scale roll-to-roll processing method powered by a steam generator to speed up manufacturing without depending on outdoor moisture, one of the researchers explained. \u201cThey are now designing a streamlined machine to achieve industrial-level fabrication,\u201d the statement added. <\/p>\n","protected":false},"excerpt":{"rendered":"
