A self-regulating liquid crystal (LC) smart window whose reflectance changes with ambient conditions is demonstrated. Thermally or optically induced switching between the transparent state and a near-infrared (NIR) reflective state can be used for energy-saving windows. Reflection of NIR can reduce the energy used for cooling, while remaining transparent to visible light. By changing the initial alignment of LCs, the window can be switched between hazy-opaque and IR-reflective states to be used for privacy windows.

使用掺有推挽式偶氮苯的液晶混合物对红外进行自我调节，以实现节能的智能窗户

展示了一种自调节液晶（LC）智能窗口，其反射率随环境条件而变化。可以在透明状态和近红外（NIR）反射状态之间进行热或光学感应切换，以用于节能窗口。NIR的反射可以减少用于冷却的能量，同时对可见光保持透明。通过更改LC的初始对齐方式，可以在不透明状态和IR反射状态之间切换窗口，以用于隐私窗口。
