Embodiment 1

[0025] Embodiment 1 has the alcohol system nano-coating liquid I of anti-reflection function

[0026]The formula of alcohol system nano-coating solution I with anti-reflection function is shown in the following table:

[0027]

[0028] Preparation:

[0029] Dissolve the dispersant and the adhesion promoter in ethanol first, add the nano particles under the condition of stirring, mix evenly, and grind in a sand mill for 3 hours to obtain a stable dispersion liquid. The particle dispersion was characterized by transmission electron microscopy (TEM), such as figure 1 shown. The TEM observation results show that the nano-silica particles are uniformly dispersed in the solvent in the original state in the obtained dispersion, and there is no obvious agglomeration.

[0030] The porogen is dissolved in ethanol, and then the above-mentioned dispersion liquid and wetting agent are sequentially added under the stirring condition, and the alcohol system nano anti-reflection coating...

Embodiment 2

[0031] Embodiment 2 Nano anti-reflection coatings of different thicknesses

[0032] Preparation method: roll-coat the nanometer anti-reflection coating solution obtained in Example 1 on the glass surface, and control the roll-coating speed and bake at 600°C for 2 minutes to form films with thicknesses of 140 nm to 150 nm, 150nm-170nm and 180nm-200nm AR coatings.

[0033] The anti-reflection performance of the obtained coating is characterized by a desktop transmittance spectrometer (Aubertai Air Floatation Desktop Spectral Transmittance Test System (Model Filmmeasure 2100). The test results obtained are shown in the following table:

[0034]

[0035]

[0036] The results show that the light transmittance of the obtained coated glass in the visible light region is higher than that of the uncoated glass, and the position corresponding to the anti-reflection peak is closely related to the film thickness.

[0037] When the film thickness is 140-150 nanometers, the light tra...

Embodiment 3

[0040] Example 3 Aqueous System Nano Anti-reflection Coating Solution and Anti-reflection Coating

[0041] The formula of the water-based nano anti-reflection coating solution with anti-reflection function is shown in the following table:

[0042]

[0043]

[0044] Preparation:

[0045] Dissolve the dispersant and the adhesion promoter in water first, add the nano particles under the condition of stirring, mix evenly, and grind in a sand mill for 8 hours to obtain a stable dispersion liquid.

[0046] The porogen is dissolved in water, and then the above-mentioned dispersion liquid and wetting agent are sequentially added under stirring condition, and the water-based nano-antireflection coating solution is obtained after stirring and mixing evenly.

[0047] The obtained nano anti-reflection coating solution is rolled onto the glass surface, and by controlling the speed of the roll coating, after baking at 700°C for 5 minutes, an anti-reflection coating with a film thickn...

Description

technical field [0001] The invention relates to the fields of chemical industry, nanomaterials, thin film preparation and clean energy, in particular to a nano anti-reflection coating solution and its preparation method and application. Background technique [0002] Now, transparent materials are widely used in various industries, such as solar cell cover glass, optical devices, etc. Due to the difference in refractive index, light will still reflect at the air / material interface when passing through transparent materials, so that it cannot pass through completely, reducing its light transmittance. For example, glass is the most common transparent material. The single-surface reflectance of ordinary glass is about 4%, so its total light transmittance is difficult to exceed 92%. For some systems that require high transparency, such as solar cells, display screens, and optical devices, the visible light loss rate of 8% will greatly affect the energy efficiency of the device. ...
