Abstract A large portion of energy consumed in buildings via infrared (IR) radiation through windows, therefore, IR blocking protection or low-emission (Low-E) window is urgently required for more energy-saving buildings. While most Low-E glass require complex and high-cost vacuum sputtering coatings, IR blocking layer that can be directly coated with cost-effective and large-scale process is desired. Herein, we report facile and scalable processing of silver nanowires/polyvinyl butyral (AgNWs/PVB) coatings for high performance Low-E windows. The spay process can be applied to create reliable IR modulation layer directly onto normal glass, and have also been expanded to roll-to-roll coating on flexible plastics. The AgNWs/PVB coating showed high transmittance of visible light (∼83.0%), high reflectivity of mid-IR (∼69.8%), low emissivity, as well as reliable chemical and mechanical durability.
