Fine-tuned gel particles enable smart windows for energy efficiency
Smart polymers can sense and react to environmental conditions, and have been used in myriad technologies for decades1. Writing in
, Li et al. report that such polymers can be used to make smart windows that strongly modulate the amount of ultraviolet, visible and — most notably — near-infrared light that enters a building. Because these components of sunlight can generate heat, this regulation could reduce the monetary and energy costs associated with heating and cooling buildings.
