Abstract
Electromagnetic interference (EMI) shielding is vital for preventing electromagnetic (EM) pollution and ensuring information security. Polymer composite foams with high conductivity and magnetic properties are recognized as ideal EMI shielding materials due to their high EM wave absorption capability, which greatly reduces the secondary pollution of the EM wave reflection. The EM wave shielding and absorption properties of conductive polymer foams (CPFs) mainly originated from their highly porous structure and the conductive paths presented on the foam skeleton, which facilitated the reflection, scattering, and attenuation of EM waves. The EMI shielding mechanisms for CPFs, the effect of CPF material composition and porous structure, the performance characterization, the fabrication of CPFs, and the advanced approaches will be introduced in this chapter.
