Development of Microwave Absorbing Materials Based on Graphene

Nowadays, electromagnetic interference receives great attention for wireless communication and charging, electronic device, and modern weapons. Materials and the various novelty structures are required and designed to absorb the emitted electromagnetic wave energy and to minimize reflection of the electromagnetic wave in certain direction. Development of graphene-based electromagnetic absorption materials are reviewed, consisting of composition materials with other carbon materials, nano-metal materials, ferrite materials, polymer materials, and non-metallic materials. The electromagnetic absorption mechanisms is briefly described and the influences of microstructure, fraction and loss mechanism on the absorption properties are discussed. The future of graphene-based electromagnetic absorption materials is also prospected.
