Preparation of the Multilayer Colorized Electromagnetic Shielding Fabric

In this paper, the electromagnetic shielding fabric with Ni-Cu-Ni three layers and colorized appearance was prepared by the electroless plating and colorized electroplating. The current density was distributed unevenly in the course of colorized electroplating, which resulted in the nonuniform color of the electroplated fabric. In this paper, this problem was solved by improving the electroplating fixture. The adhesion strength and the conductivity of the coating were measured respectively. The results showed that the Ni-Cu-Ni multilayered coating possessed stronger adhesion strength to the fabric substrate than single layered coating, and the conductivity of coating was better than that of pure metal.
