Electromagnetic Interference Shielding Effectiveness of Multilayer Envelope Materials of Vacuum Insulation Panels Used in Building

摘要：

　　The shielding characteristic of multilayer envelope materials of vacuum insulation panels (VIPs) was analyzed based on the electromagnetic interference shielding theory of Schelkunoff.The kind of multilayer envelope materials were designed and investigated with observation of microstructure by SEM and testing of shielding effectiveness (SE).Results show that the envelope materials of VIPs can be used to achieve effective shielding,and the SE of envelope materials with aluminum foil plays an important role in shielding performance.In addition,the absolute value of SE is relatively higher in the high frequency and the SE increases almost linearly with the increase of A1foil thickness in the envelopes under the condition of higher frequency.
