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.
