Abstract

The invention discloses a sensitization-free chemical nickel-plating method of conducting glass and belongs to the technical field of chemical plating. The sensitization-free chemical nickel-plating method of conducting glass is suitable for chemical nickel-plating of indium tin oxid (ITO) conducting glass and fluorine-doped tin oxide (FTO) conducting glass. The sensitization-free chemical nickel-plating method of conducting glass comprises six steps of oil removal, coarsening, glue removal, catalysis, activation and chemical nickel-plating. The sensitization-free chemical nickel-plating method is a nickel-plating method suitable for conducting glass and having good selectivity to a glass conducting surface. A planting layer obtained by the method has good adhesion with base glass and high brightness and can obviously improve conductivity of a glass conducting surface. The sensitization-free chemical nickel-plating method of conducting glass adopts raw materials having a wide source and low costs, and is suitable for metallization treatment on mobile communication terminal capacitive touch screen (ITO, FTO) line terminals.

Description

technical field [0001] The non-sensitizing chemical nickel plating method of the present invention belongs to the preparation method for obtaining metal nickel plating on the conductive surface of conductive glass. This method has good selectivity to the conductive surface of the conductive glass, and the coating is selectively deposited only on the conductive surface (circuits and terminals). Background technique [0002] Indium-Tin-Oxide or Tin-doped Indium Oxide film is a heavily doped, highly degenerate n-type semiconductor, referred to as ITO film. At present, the electron density of ITO film can be as high as 10 21 / cm 3 , electron mobility between 15 and 450 cm 2 / Vs range, the resistivity can be as low as 7×10 -5 Ω·cm, the transmittance to visible light is above 90%, and the reflectance to infrared light is above 90%. [0003] Fluorine-doped Tin Oxide film (Fluorine-doped Tin Oxide) is a wide bandgap oxide semiconductor transparent to visible light, with a band...
