Molecular force to achieve the effect of permanent antifouling. [Previous technology] ^ In recent years, with the development of high-tech industries, the requirements for the quality of optical information and optical communication components have become higher and higher. Among them, optical films are the key technology in optical component equipment. Especially applied to flat display, its quality has certain requirements, such as high light transmittance, low reflectivity and other optical properties; and light weight, thin thickness and other characteristics to meet the light and thin characteristics of the display trend; and At the same time, it has physical properties such as high hardness, high abrasion resistance, and high antifouling effect to provide good protection for flat displays. ′. The structure of a commonly used optical film is shown in FIG. 丨. The optical film includes a substrate 110, a hard coat layer 12 and an anti-reflection layer 130. The hardened layer 120 can increase the hardness of the optical film to protect the internal structure of the display. The anti-reflection layer 130 can reduce the reflectivity and increase the transmittance of the surface. However, this optical film is generally placed on the outer layer of a display and is easily contaminated. Another type of optical film as shown in FIG. 2 is to add an anti-reflective layer 23o between the hardened layer 22o and the antifouling layer 240 to reduce the reflectance. Although this optical film can provide better optical quality, it will increase the overall thickness of the optical film, and because the hardened layer 22 is manufactured by wet precision coating, the anti-reflection layer 230 is an inorganic coating. The antifouling layer 24 is manufactured by a method and wet precision coating, so the manufacturing process is very complicated and the cost is quite high. In addition, the general antifouling layer is applied by the dipping method, that is, the substrate to be coated with the antifouling layer is vertically placed in the antifouling layer soaking solution, and then 5 1224202 is taken out vertically. Both will contain coatings; but if the product only needs to be coated on one side, this method will not be applicable. For example, the transparent conductive film for touch panels requires an antifouling layer because the outer layer is often in contact with the outside world. However, the inner layer of indium tin oxide (ITO) conductive glass layer does not need to be coated, and a single-layer coating method is needed to coat the antifouling layer. In order to better meet market demands, an optical film with a low reflectivity, a simple process, and a single-layer coating is an important research topic. [Summary of the Invention] In view of this, the object of the present invention is to provide a φ structure of a composite functional optical film and a manufacturing method thereof.

Increasing transmittance and decreasing refractive index can also increase the contact angle of this antifouling layer to achieve the effect of permanent antifouling. In addition, since the present invention uses two particles in the hardened layer to make the compound in the antifouling layer have a fluorine functional end toward the upper surface of the antifouling layer to achieve a permanent antifouling effect, the compound in the antifouling layer is a single Layer type This antifouling layer has the most antifouling efficiency.
