Abstract
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.
Highlights
Solar energy is a continuous source of renewable energy
We investigated the effect of TiO2 film with different argon oxygen ratios on photocatalysis
The hydrophilic properties of the films were evaluated by measuring their water contact angles (WCAs) using a contact angle measuring instrument (KRUSS DSA25)
Summary
Solar energy is a continuous source of renewable energy. Human beings mainly live by the thermal radiation provided by the sun. More than 89% of the infrared emissive energy is absorbed by the glass, resulting in the rise of the glass temperature, and a large amount of heat is dissipated through the heat exchange between the glass and the surrounding air, resulting in a large amount of outdoor heat brought by sunlight entering the room or a large part of indoor heat escaping to the outside (Granqvist, 2007; Dalapati et al, 2018) These conditions have seriously increased the burden of air conditioning and wasted a lot of energy. Hydrophilic materials are generally vulnerable to organic compounds, especially compounds with polar functional groups To overcome this problem, surface-coated glass is endowed with hydrophilic and photocatalytic properties (Oladipo et al, 2019); the self-cleaning behavior of surface-coated glass becomes more prominent. We investigated the effect of TiO2 film with different argon oxygen ratios on photocatalysis
