Abstract

AbstractElectromagnetic interference (EMI) emitted from various electronic and communication devices is a serious problem that has harmful effects on the smooth functioning of electronic, human health as well as the surrounding environment. In this concern, lightweight EMI shielding materials are urgently required to solve increasingly serious electromagnetic pollutions. Recently, lightweight carbon foams have attracted worldwide interest due to their outstanding properties such as lightweight, interconnected porosity, high surface area, corrosion resistance, superior electrical and thermal properties that are highly useful for suppressing electromagnetic noises. This chapter covers the up to date research on the EMI shielding performance of phenolic resin-based carbon foam reinforced with various conducting and magnetic fillers. The synergistic effect of the conducting and magnetic fillers may render tunable electrical percolation phenomena in phenolic-based foams. The EMI shielding of carbon foams reinforced with various fillers is summarized by tables in this chapter, which will provide readers useful information. In the last section, current challenges and future research directions of this growing field are also discussed.KeywordsPhenolic resinCarbon foamCNTsGrapheneConducting and magnetic fillersEMI shielding
