JEDDAH: A research team of King Abdullah University of Science and Technology (KAUST) has developed a superabsorbent eco-friendly polymer film that harnesses solar energy to provide cooling solutions, the Saudi Press Agency (SPA) reported on Tuesday.
This solution can help reduce carbon emissions, heat stress, and electricity consumption amidst the growing impact of climate change.
The KAUST team finds a solution that combines evaporative and radiative cooling, eliminating the need for extra chemicals or energy. This provides an eco-friendly alternative to air conditioning.

The technology uses evaporative cooling leverages water vaporization to reduce temperatures.
This approach utilizes sodium polyacrylate which absorbs ambient moisture, forming a reflective white film that prevents solar heating.
According to the study the film temperatures could be reduced by nine degrees Fahrenheit (five degrees Celsius) without electricity. The technology reduces reliance on air conditioners, leading to substantial reductions in carbon emissions, enhanced economic feasibility and lower electricity bills.
The SPA said the KAUST researchers continue to improve this film and develop cheaper and faster manufacturing methods, to apply this cooling technology to the roofs of buildings, solar panels, light-emitting diodes and batteries.
