Problems solved by technology

[0004] Although the application of US Patent Publication No. US 2006 / 0029818A can take into account both low reflectivity and antistatic effect, the manufacturing process of the composite film structure requires multiple coating, drying or laminating processes, which greatly increases the complexity of the process, not only Increasing the time of the manufacturing process can also easily lead to a decrease in the yield of the process

Embodiment 1

[0043] Please refer to Figure 4 , Figure 4 It is the reaction flow schematic diagram of embodiment 1. First, take about 20.8 grams of tetraethoxysilane (TEOS), about 7 grams of tridecafluoro-1,1,2,2-tetrahydrooctyl-trimethoxysilane, and about 20 grams of isopropanol (IPA) as a reaction solvent. g with 0.1N hydrochloric acid solution (HCl (aq) ) about 7 grams in a reaction bottle, stirred with a stirrer at room temperature for 30 minutes until completely homogeneous, then stopped stirring, and continued to react the homogeneous transparent solution at a reaction temperature of 70°C for 2 hours, and then mixed the solution Bring to room temperature.

[0044] Next, pour about 3 grams of dextrose (D-glucose) aqueous solution (concentration is about 0.8 moles per liter) that has been prepared in advance into the above-mentioned viscous mixed solution and stir vigorously until it is homogeneous, and another about 7 grams The polyaniline aqueous solution (with a solid content o...

Embodiment 2

[0048] The reaction process of embodiment 2 is similar to the reaction process of embodiment 1, but the increment of tridecafluoro-1,1,2,2-tetrahydrooctyl-trimethoxysilane added in embodiment 2 is about 10 grams , and the added polyaniline aqueous solution was reduced to about 5 grams, and after Figure 4 Transparent optical films were produced following the procedure shown.

Abstract

The invention relates to a multifunctional optical film and a manufacturing method thereof. The optical film has the functions of low reflectivity, static electricity resistance and oil stain resistance. The manufacturing method of the optical film in the invention comprises the following steps: mixing alkoxy silane, fluorine-modified alkoxy silane, conducting material and hole forming agent to form masking liquid; and solidifying the masking liquid to form the optical film. The optical film has fluoric siloxane, conducting material doped in the siloxane, and three-dimensional tiny pores. Therefore, the optical film has the functions of oil stain resistance, static electricity resistance and reflection resistance.

Description

technical field [0001] The invention relates to an optical film and a manufacturing method thereof, which can simultaneously provide composite functions of anti-reflection, anti-fouling and anti-static. Background technique [0002] In existing display devices, in order to avoid image interference by reflected light, a layer of low reflection (lowreflection) reflective layer is usually coated on the surface of each substrate or each film layer of the existing display device to reduce the reflectivity. . However, the material of the low-reflection layer generally contains insulating resin, so it is particularly easy to accumulate charges on the surface to generate surface static electricity, which in turn causes pollution problems such as dust adsorption. In order to reduce the pollution caused by static electricity, conductive antistatic agents, such as ionic surfactants or conductive polymers, or metal oxide particles, such as zinc oxide (ZnO) and tin oxide, are generally ...
