Research Progress in Electromagnetic Shielding Materials

Based on the electromagnetic shielding theory,the electric conductivity, magnetic conductivity, and thicknesses of the electromagnetic shielding materials are decisive factors to their shielding performance. Ferromagnetic materials, fine conductor metal,surface-spreading film materials coated metal,composite materials filled electrical conductive fibers, and silver,nickel,carbon electrical conductive dopes are the main research content in the field of electromagnetic shielding materials at present. In this paper,the research progress,performance,application,and advantages and disadvantages are reviewed. Finally,the developing trends in the future are predicted.
