Abstract
The invention provides a transparent conductive material for wideband shielding. The material includes a metal mesh layer of which a surface is successively electroplated with a conductive metal layer and a magnetic conductibility metal layer. An external surface of the metal layer is provided with a blackening layer. The metal mesh layer adopts a self-assembling nanometer silver slurry in coating the surface of a film and uses the nanometer silver slurry self-assembling function to form a mesh figure. The metal mesh layer is formed by nanometer silver slurry screen printing or silvering metal layer etching mesh method. The conductive metal layer is copper or silver or gold. The magnetic conductibility metal layer is iron or nickel, or iron-nickel alloy or nickel cobalt alloy. The blackening layer is electroplated by a tin-nickel alloy or is immersed in a blackening liquid. According to the invention, the material overcomes the problem of low effectiveness of low frequency shielding of current windows, and can meet requirements for electromagnetic shielding f high and low bandwidth frequency band.
