Super-hydrophilic and solar-heat-reflective coatings for smart windows

► Multilayer coatings for hydrophilic and solar-heat-reflective functions on glass ► Thin, heat-resistant silver alloy layer facilitated the formation of anatase. ► Photo-induced hydrophilicity was achieved using a top anatase layer. ► Drastic drop of water contact angle under UV irradiation obtained for some samples ► Excellent spectral selectivity of the TiO2/SiO2/Ag alloy/SiO2/Ag coating for daylight
