The liquid crystal dimming film is used as one of liquid crystal display functional films, and when the power is off, the polymer liquid crystals which are arranged in disorder can repeatedly refract light rays in the film, so that the transmitted light cannot penetrate through the film material and presents a milky opaque state; when the film is electrified, the polymer liquid crystals are orderly arranged along the direction of the electric field, so that light can easily pass through the film material, and a colorless and transparent state is presented. By switching the electric signals, the film material can be instantly switched between transparent and non-transparent.
However, the conventional touch material indium tin oxide is difficult to overcome the defects of low transmittance and the like, and is difficult to develop on a large-size liquid crystal dimming film. However, the replacement, the nanowire, due to the limitation that it must be coated on a thin film, and the indium tin oxide that can be directly coated on the glass add many disadvantages, such as more complicated process, higher cost, etc.

Examples of the experiments
Transmittance and sheet resistance are the main references used to evaluate optical and electrical properties.
The touch area material selects the nano silver wire with the length-diameter ratio of 1000 as a main conductive material, the influence of the addition amount of other materials on the transmittance and the sheet resistance is researched, and the result refers to table 1.
TABLE 1
Experimental group | Nano silver wire (g) | Water (g) | Ethanol (g) | Isopropanol (g) | Transmittance (%) | Square resistance (omega/□) |
Experimental group 1 | 1 | 40 | 30 | 30 | 90 | 180 |
Experimental group 2 | 2 | 40 | 30 | 30 | 88 | 110 |
Experimental group 3 | 4 | 40 | 30 | 30 | 85 | 45 |

Experimental group 6 | 4 | 10 | 45 | 45 | 82 | 120 |
As can be seen from table 1, the addition of a larger amount of silver nanowires can better improve the conductivity, but has a certain effect on the transmittance; a small amount of nano silver wires are added, so that higher transmittance can be obtained, but the conductivity can be lost to a certain extent.
In addition, the nano silver wires can be better dispersed by adding water, and the leveling can be better realized by adding ethanol and isopropanol, so that the nano silver wires can be better spread on the surface of the EVA laminated adhesive. As can be seen from experiment groups 3, 5, and 6 in table 1, when too much water was added, the silver wire could not be leveled, and both conductivity and transmittance were affected to some extent. The excessive ethanol and isopropanol are added, so that the nano silver wires cannot be uniformly dispersed in the solution, the film-forming silver wires are not uniformly dispersed, and the conductivity is obviously reduced.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
