Embodiment 1

[0019] Preparation system: Magnetron sputtering preparation technology is adopted. The magnetron sputtering system consists of a transition chamber and a main sputtering chamber (45 cm in diameter). The main sputtering chamber is connected with a molecular diffusion pump, and the ultimate vacuum is 2.0×10 -6 Pa. The sputtering chamber has three target positions for three different 2-inch diameter targets. Each target position is inclined upward at an angle of 30°, and can be co-sputtered upwards in a confocal manner or sputtered upwards in a three-target independent manner. The sample stage can be heated up to over 600°C and can keep rotating continuously during the sputtering process.

[0020] Substrate treatment: In the experiment, the substrate was made of float glass. The substrate was ultrasonically cleaned in anhydrous alcohol and acetone for 5 minutes successively, after drying, it was fixed on the sample carrier and placed in a transitional vacuum chamber for vacuu...

Embodiment 2

[0026] The preparation system, substrate treatment, and preparation methods are the same as in Example 1.

[0027] Preparation conditions: TiO 2 The preparation conditions were exactly the same as in Example 1, and the sputtering power of Ag was increased to 12W to increase the loading of Ag nanoparticles in the film layer (about 22%).

[0028] The thus prepared coated glass exhibits a light purple color. After the glass is exposed to sunlight, the film surface has good hydrophilicity.

Embodiment 3

[0030] The preparation system, substrate treatment, and preparation methods are the same as in Example 1.

[0031] Preparation conditions: TiO 2 The preparation conditions were exactly the same as in Example 1, and the sputtering power of Ag was increased to 18W, which further increased the loading of Ag nanoparticles in the film layer (about 43%). The diameters of Ag nanoparticles are mainly distributed between 70 and 160 nm, and they are uniformly distributed in TiO 2 In the film

[0032] The thus-prepared coated glass exhibits a purplish red color. After the glass is exposed to sunlight, the film surface has good hydrophilicity.

Abstract

The invention provides a colorful self-cleaning coated glass, which comprises a glass substrate (1), titanium dioxide film (2) and noble metal nano-particles (3), wherein, the titanium dioxide film deposits on the surface of the glass substrate, the noble metal nano-particles are uniformly or non-uniformly intermingled in the titanium dioxide film layer or on the interface. The noble metal nano-particles are mainly gold, silver, copper, etc., which are intermingled into the titanium dioxide for leading the film to present different colors and the glass to generate favorable visual effect. Therefore, the colorful self-cleaning coated glass can not only beautify the appearance of the buildings and help improve the indoor lighting effect, but also promote the commercial value of the titanium oxide self-cleaning coated glass.

Description

technical field [0001] The invention belongs to the technical field of glass materials, in particular to a colored self-cleaning coated glass. technical background [0002] Among many photocatalytic materials, titanium dioxide not only has high activity and good chemical stability, but also has low material cost and is environmentally friendly, so it is highly valued by people. It is currently the most widely used nano-photocatalytic material and the most promising one. Green environment-friendly catalyst. [0003] Coating a layer of nano-titanium dioxide film on the surface of ordinary glass, the glass surface has a self-cleaning function. The self-cleaning function of glass means that under the excitation of ultraviolet or visible light, the glass has superhydrophilicity. After the glass is showered with water, water droplets will not condense on the surface of the glass (or the contact angle between the water droplets and the glass surface is very small). In addition, ...
