Abstract

Graphene is composed of a single atomic layer of carbon with excellent mechanical, electrical, and optical properties. It can be widely used in the areas of physics, chemistry, energy, information, equipment manufacturing, and electromagnetic interference shielding. This chapter described the concepts, structures, properties, manufacturing methods, and applications of graphene composites in shielding against electromagnetic interference. The continuous 3D conductive array of graphene composites can effectively improve the electronic and ionic transmission of the material. Therefore, adding graphene oxide to the composite material will significantly improve the performance of the material for better conduction and EMI shielding. This chapter summarizes the latest developments in the electromagnetic shielding performance of graphene composites and highlights their prospects.
