A series of smart window coated multifunctional NIR shielding-photocatalytic films were fabricated successfully through Kx WO3 and F-TiO2 in a low-cost and environmentally friendly process. Based on the synergistic effect of Kx WO3 and F-TiO2, the optimal proportion of Kx WO3 to F-TiO2 was investigated and the FT/2KWO nanocomposite film exhibited strong near-infrared, ultraviolet light shielding ability, good visible light transmittance, high photocatalytic activity and excellent hydrophilic capacity. This film exhibited better thermal insulation capacity than ITO and higher photocatalytic activity than P25. Meanwhile, the excellent stability of this film was examined by the cycle photocatalytic degradation and thermal insulation experiments. Overall, this work is expected to provide a possibility in integrating Kx WO3 with F-TiO2, so as to obtain a multifunctional NIR shielding-photocatalytic nanocomposite film in helping solve the energy crisis and deteriorating environmental issues.
