Electromagnetic shielding materials can limit the transmission of electromagnetic energy, avoid the electromagnetic interference and reduce the risk of leakage. Therefore, they are increasingly used in the military and civil fields. With unique two-dimensional structure and excellent physical and chemical properties, graphene fits the rapid development of flexible electronic devices well. Based on the theory of electromagnetic shielding, this paper involves the design ideas and preparation methods according to the classification of pure and composite graphene films, reviews the research progress of graphene-based electromagnetic shielding film materials in recent years, and prospects its development in view of the application needs.
