Problems solved by technology

[0004] At present, in order to improve the electromagnetic shielding performance, microwave absorption performance, and electrical conductivity of conductive sponges used for electromagnetic shielding and wave absorption, metal silver, metal copper, metal nickel, nickel-coated copper, nickel-copper-nickel are generally deposited on the surface of the sponge. conductive layer, but the above-mentioned conductive layer has the following disadvantages: the surface of the conductive layer of metal copper and metal silver is easy to oxidize and discolor, and its conductivity and aesthetics will soon decline; when using a nickel metal conductive layer to coat sponge or other metal conductive layers , the surface is silvery white, easy to be dirty, and poor in decoration, especially in some special occasions, such as electrical cooling vents or occasions that require materials to have certain light-absorbing and shading properties, it is very unsuitable
