A highly visible-transparent thermochromic smart window with broadband infrared modulation for all-season energy savings.

ABSTRACT: Thermochromic smart windows effectively reduce the energy consumption for buildings through passive light modulation including the transmission of visible (T_Vis) and near-infrared (T_NIR) light, and the emissivity of mid-infrared (ε_MIR) light in response to ambient temperature change. However, thermochromic windows that maintain high T_Vis while modulating T_NIR and ε_MIR simultaneously are highly desirable but still challenging. Here, we develop a thermochromic smart window based on a two-way shape memory polymer to enable reversible transformation and achieve T_NIR modulation of 44.0% and ε_MIR modulation of 76.5% while maintaining high T_Vis (>50%). Compared to traditional windows based on silica
