For ordinary glass, more than 89% of the infrared emission energy is absorbed by the glass, causing the temperature of the glass to rise, and then a large amount of heat is lost through the heat exchange between the glass and the surrounding air, causing a large amount of heat from the outside to enter the room or A large part of the indoor heat leaks out, which seriously increases the burden on the air conditioner and wastes a lot of energy

Abstract
The invention discloses a composite film material which is formed by compounding a plurality of film layers, the basic structure of the composite film material is [A / B / C / D], the material of the film layer A is selected from WO3, ZnO or Ta2O5; the material of the B film layer is selected from metal elements of VIB family and metal elements of IB family; the material of the C film layer is selected from NiCr alloy, Si3N4, AlN and SiC; and the material of the film layer D is selected from titanium dioxide, zincoxide, zirconium dioxide or tinoxide. The total thickness of the composite film material is 300 to 325 nm. The multi-layer compounding can be realized through direct current magnetron sputteringcoating. The composite film material disclosed by the invention has multiple effects of photo-thermal, self-cleaning, photocatalysis and the like, not only has relatively low infrared projection rate and relatively good photoinduced hydrophilicity, but also has excellent photocatalytic performance; the material can be used as or used for preparing a material with an infrared light absorption reducing effect, a material with a self-cleaning effect, a material with a printing and dyeingwastewaterphotocatalytic degradation effect and a material with a micro-plastic photocatalytic degradation effect.
Description
technical field [0001] The invention relates to a composite film material with multiple functions, a preparation method thereof, and its application in reducing infrared light absorption, film layer self-cleaning and photocatalytic degradation of printing and dyeingwastewater and microplastic treatment, and relates to photothermal, photocatalytic treatment , Self-cleaning technology field. Background technique [0002] Solar energy is a sustainable and renewable source, and humans mainly rely on the thermal radiation provided by the sun to survive. For ordinary glass, more than 89% of the infrared emission energy is absorbed by the glass, causing the temperature of the glass to rise, and then 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 the indoor heat is leaked out, which seriously increases the burden of the air...
