Graphene is widely considered a promising candidate for microwave absorbing materials in the future due to its unique dielectric properties, high specific surface area, low density and other outstanding properties. However, the single component graphene has poor microwave absorbing properties, so graphene-based microwave absorbing composites have become a research hotspot in recent years. In this paper, microwave absorbing mechanism and characteristics of graphene and its composites were introduced. Accordingly, it indicates that dielectric graphene microwave absorbing composites have the potential to become lightweight, high-intensity, broadband, and thin-layer microwave absorbing materials.The research progress in dielectric graphene microwave absorbing composites was reviewed from two aspects of graphene matrix and dopant.Finally, it was pointed out that developing new dielectric dopants with strong loss ability, constructing microwave absorbing composites with multiple components, establishing common design methods, as well as exploring large scale preparation methods would become the research trends in the future.
