The present invention relates to a method for producing a broadband electromagnetic wave absorber material using a soluble polyaniline salt or a polyalkoxyaniline salt. In particular, a polyaniline salt or polyalkoxyaniline salt, which is a conductive polymer, is dissolved in an environmentally friendly solvent or a general organic solvent. Or by using a polyaniline salt or polyalkoxyaniline salt solution in which a magnetic or carbon mixture is mixed with a polyaniline salt or polyalkoxyaniline salt solution, and the solution is processed into an electromagnetic wave absorber paint, spray, or the like. By coating on electronics, semiconductors, information and communication devices, mobile phones and mobile communication device cases (cases), or polymer-based fibers to produce a non-woven fabric for electromagnetic wave absorbers. As the magnetic material and the carbon mixture, magnetic materials such as nickel (Ni), iron (Fe), ferrite, and ceramic materials, and carbon mixtures such as carbon black and graphite are preferable. Fibers of the polyester (Polyester), nylon (Nylon), Orlon (Orlon), acrylic (Acrilan), cotton (Cotton), Dynema (Dynema) and the like are preferable. The present invention can produce a material for the electromagnetic wave absorber which is low in the working environment and price according to the environmentally friendly solvent, excellent mechanical properties, mechanical stress does not occur. |
