As outdoor electronic devices face increasing heat loads and fire safety risks, traditional cooling methods like fans and air conditioners fall short in energy efficiency and environmental sustainability. Now, researchers from Central South University and Brown University, led by Professor Meijie Chen, have developed a breakthrough all-in-one photonic hydrogel that combines radiative cooling (RC) and evaporative cooling (EC) for above-ambient heat dissipation and enhanced flame retardancy.
