To improve the sunlight transmittance and infrared reflectivity, different membrane compositions are designed to realize self-cleaning and low emissivity of the membrane. The WO3/Mo/CrNi/TiO2 composite film was prepared by magnetron sputtering technology, and the complementary effect of these films with four different argon/oxygen ratios of TiO2 layer and different film thicknesses was analyzed. The microstructure characterization proves that the self-cleaning function of the composite film is determined by the photocatalytic properties and superhydrophilic properties of the TiO2.
