Low-loss nanometer touch control film

Abstract

The invention discloses a low-loss nanometer touch control film, which is prepared by the following steps of 1, soaking a substrate into an alcoholic solution; and using distilled water for cleaning and drying after ultrasonic cleaning; 2, coating a transparent tin indium oxide solution onto the surface of the substrate to obtain a transparent tin indium oxide film; 3, installing a conducting wiremold onto the upper end of the transparent tin indium oxide film; and then, pouring a mixed silver slurry solution to obtain a conduction network of a nanometer structure; 4, adding the conduction network in the step 3 for micro curing to form a conduction wire network; 5, after mold removal, performing heating pressurized restoration reaction on the conduction wire network to form a fine conduction wire network; and 6, performing protection film curing on fine conduction wires, and obtaining a product of the nanometer touch control film after heating curing. The low-loss nanometer touch control film has the advantages that the preparation method is simple; the problems of low flatness, low uniformity, great defect, high roughness degree and the like of the material are solved; the prospective application is realized; and the cost advantage which cannot be surpassed by the existing industry technology is realized.

Description

technical field [0001] The invention belongs to the technical field of nano-materials, and in particular relates to a low-loss nano-touch film. Background technique [0002] Nano-touch film is a sensing film mainly encapsulated with nano-wires. It integrates multiple functions such as precise sensing positioning, flexibility, and high transparency. It is used for precise touch positioning of touch screens above 10 inches. Interactive projection and security positioning. At present, there is no equipment on the market that can independently and completely produce nano-touch film on a large scale. Its production is still in the stage of small scale test. The limitation of the operation process is more complicated, the assembly line production is not easy, the waste of manpower and material resources, and the yield rate is not easy to control. Moreover, the existing ITO conductive films in the world are small in size and low in transparency, and their products are monopolized...
