Graphene films (GFs) featured with exceptional electrical property and macroscopic ultrathin two-dimensional structure demonstrate infinite potentials for electromagnetic interference shielding applications. By retrospecting the advanced achievements of GF-type shielding materials over the past decades, this review aims to provide a roadmap driven by the great progress and inspire future disruptive innovations. The fabrication methods of GFs are systematically discussed, with a particular emphasis on creative approaches. Strategies to optimize the shielding performance are elaborated in terms of manufacturing methods, shielding efficiency and properties, corresponding mechanisms, challenges and perspectives. Likewise, advancements of multifunctional GFs simultaneously satisfying electromagnetic shielding with thermal dissipation or transparent requirements are outlined. Using history as a mirror, a clear insight into this rapidly growing field is given, and corresponding current challenges and future opportunities in the fabrication and application of GF-family shielding materials are highlighted and envisioned. We hope this review can encourage further innovations in this exciting branch of research and inspire scientists from both academia and industry to promote revolutionary breakthroughs in GF-shields for next-generation shielding applications.
