If there is a chemical formula in this case, please reveal the chemical formula that best shows the characteristics of the invention: [Description of the Invention] [Technical Field] The present invention describes a near-field electrospinning technique, in particular, emphasizing near-field electrospinning and controlling metal nanowire spacing, metal nanowire diameter, and metal nanowire stacking height , light transmission ^ and guide [Prior Art] 201226644 Indium tin oxide στο) is a mixture of indium oxide (In2〇3) and tin (IV) oxide (Sn〇2), usually 90% by mass In2 〇3,10% Sn〇2. It is transparent and colorless in the form of a film, but it is yellowish gray in the block state. The main characteristic of indium tin oxide is its combination of electrical, conductive and optical properties. However, compromises are needed in thin failures because high concentrations of charge carriers will increase the conductivity of the material, but will reduce its transparency. Indium tin oxide thin films are most commonly deposited onto the surface by electron beam evaporation, physical vapor deposition, or by some deposition techniques. Because of the high price and limited supply of indium, the lack of brittleness and softness of the IT layer, and the high cost of vacuum, other alternatives are being sought. The solution that has arisen in recent years is to make the carbon nanotubes or silver-nine, because at the junction of low resistance, the structure of the rice can effectively reduce the sheet resistance, but the resistance of the interface between the carbon nanotubes and the graphite is too high; The aspect ratio of the silver nanowire is limited to approaching 1〇〇, and the silver phase is expensive. The following five major losses are caused: (1) The high price of tin oxide, brittleness, and high vacuum deposition are their limitations. (2) High concentration of charm 2 will increase the machine's electrical rotation, but will reduce its transparency. (3) The resistance of the interface between the carbon nanotubes and the graphite is too high; the aspect ratio of the secret is limited to close to 100, and the silver is relatively expensive. (4) It is impossible to accurately control the aspect ratio, pitch, wire diameter, etc. of the metal nanowire. (5) Cannot be applied to flexible boards.
