PURPOSE: To improve shielding effect for interrupting an incident electromagnetic wave with reflection and/or absorption by coating the powdered or granular metallic materials with intrinsic conductive polymer-formed materials. CONSTITUTION: The powdered or granular or flaky or fibrous metallic materials are peculiarly coated by the conductive polymer-formed materials. The powered or granular metallic materials are desirable to have the aspect ratio of 1-10000 and average diameter or average length of 0.1-500μm, and it is desirable that they have the average diameter or the average length of 10-300μm. Since plural coating layers are desirable to be combined and used for the coating layers, the plural coating layers are combined and coated. But, at least one of the coating layers is coated by the coating layer being intrinsic conductive polymer. Thus, shielding effect for interrupting the incident electromagnetic wave can be improved by reflection and/or absorption. |
