With the continuous development of information technology and electronic communications, electromagnetic pollution caused by various electronic devices is widely concerned by society, and thus the electromagnetic interference(EMI) shielding materials have recently become a research hotspot. In recent years,carbon-based EMI shielding materials have been greatly developed. In particular, graphene, a two-dimensional material with a thickness of one atom, has unique properties such as good electrical conductivity,light weight, stable chemical properties, environmental friendliness, easy processing, and ultrahigh specific surface area, and is considered as a candidate material for new EMI shielding materials. The uses of graphene as EMI shielding materials in nano-composites, films, foams and aerogels are summarized. Combining with the research status, the challenges and future development of graphene based EMI shielding materials are discussed and prospected.
