Abstract

In this study, paneled conductive plasterboards composed of a conductive mesh sheet, carbon powders and some carbon fibers are discussed about their electromagnetic shielding efficiency for buildings. As a result, it could be obtained that the shielding efficiency of the panels was over 30dB between 30MHz to 10GHz, and the efficiency of their joint part, which caused shielding troubles for usual joint methods, was not lower than that of copper leaf. Thus, we established that the panels could be sufficiently applicable for simple electromagnetic shield buildings.
