建筑物中很大一部分能量是通过窗户的红外辐射消耗的，因此，红外阻挡保护或低辐射（Low-E）窗户是更节能的建筑物的迫切需要。虽然大多数Low-E玻璃需要复杂且高成本的真空溅射涂层，但需要可以通过具有成本效益的大规模工艺直接涂覆的IR阻挡层。在此，我们报告了用于高性能Low-E窗口的银纳米线/聚乙烯醇缩丁醛（AgNWs/PVB）涂层的简易和可扩展的处理。斯帕伊工艺可用于直接在普通玻璃上形成可靠的红外调制层，也已扩展到柔性塑料上的卷对卷涂层。AgNWs/PVB涂层显示出高的可见光透过率（接近83.0%）、高的中红外反射率（接近69.8%）、低的发射率以及可靠的化学和机械耐久性。
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 (similar to 83.0%), high reflectivity of mid-IR (similar to 69.8%), low emissivity, as well as reliable chemical and mechanical durability.
