Abstract

The invention discloses a low-loss nanometer touch film, which comprises the following steps of 1: dipping a base material into alcoholic solution, cleaning with distilled water after ultrasonic cleaning is carried out, and carrying out airing; 2: coating the surface of the base material with transparent indium tin oxide liquid to obtain a transparent indium tin oxide film; 3: arranging a wire mould on the upper end of the transparent indium tin oxide film, and then, pouring mixed silver paste solution to obtain a conductive network of a nanometer structure; 4: adding micro-solidification to the conductive network in the step 3 to form a conductive filament network; 5: after mould removal is carried out, carrying out heating, pressurization and repairing reaction on the conductive filament network to form a fine conductive filament network; and 6: carrying out protective film solidification on a fine conductive filament, and carrying out heating solidification to obtain the product nanometer touch film. The preparation method is simple, the problems of low flatness and evenness, big defect, high roughness and the like of the material are solved, and the low-loss nanometer touch film is prospective and has the advantage of low cost which is unsurpassable for an existing industry technology.

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...
