Problems solved by technology

The application number is 201280036901.5, which discloses a preparation method of a TCO material similar to ATO, and obtains a composite film with near-infrared modulation capability. Dissolution and washing are the key steps of this technology. It is precisely because of these steps that the loss rate of TCO nanoparticles is high, and the material preparation time is long, which is not suitable for industrial mass production

Abstract

The invention discloses a method for preparing an antimony-doped tin oxide electrochromic film. The method particularly comprises the following steps: step 1, preparing a spray liquid: firstly, addingantimony butter into acetylacetone, then, adding tin chloride pentahydrate, adding acetic anhydride after the obtained mixed solution is cooled to the room temperature, performing stirring for 30 minat the room temperature, finally, adding absolute ethyl alcohol, and performing stirring for 20 min at the room temperature to obtain an ATO spray liquid; step 2, preparing an ATO film: at first, placing a soda-lime glass substrate into a heating furnace, heating the soda-lime glass substrate up to 350-450 DEG C, driving the soda-lime glass substrate to translate into a spray room by means of a transmission device, using an ultrasonic spray gun to spray the ATO spray liquid, prepared in step 1, onto the soda-lime glass substrate by taking nitrogen as a carrier gas, performing cooling with strong wind after ending of spraying, and unloading coated glass to finally obtain the antimony-doped tin oxide electrochromic film. The method is simple in process and does not need a special vacuum environment or a reaction room.

Description

technical field [0001] The invention belongs to the technical field of optoelectronics, and in particular relates to a preparation method of an antimony-doped tin oxide electrochromic film. Background technique [0002] Antimony Tin Oxide (ATO) thin film is widely used in building energy-saving glass because of its strong corrosion resistance, good electrical conductivity, high visible light transmittance, ultraviolet cutoff and high mid- and far-infrared reflection. It can be plated on the surface of ordinary transparent glass to prepare low-emissivity glass (Low-e glass) with thermal insulation performance. Traditional Low-e glass has high transmittance in the visible spectrum and high reflectivity in the mid- and far-infrared bands, which can ensure indoor lighting while isolating mid- and far-infrared radiant heat. However, the heat radiation of the sun is mainly concentrated in the near-infrared band. As people's pursuit of living comfort is getting higher and higher, ...
