Scientists develop nanocellulose-based aerogel film to keep buildings cooler

(Nanowerk News) The global demand for cooling energy has seen a surge in the 21st century. Notably, the use of air conditioners and electric fans accounts for nearly 20% of a building’s overall electricity consumption. Exploring eco-friendly and sustainable cooling technologies holds promising prospects for combatting global warming and curbing energy usage. In a study published in the KeAi journal Journal of Bioresources and Bioproducts (“Large scalable, ultrathin and self-cleaning cellulose aerogel film for daytime radiative cooling”), a team of Chinese researchers…
